MIcro Modular Patches

MIcro Modular Patches from Rastko Lazic on Vimeo.

"On my journey to Myanmar I could not take a lot of instruments with me.

One of the instruments I do have with me is the Nord Micro Modular (http://www.vintagesynth.com/clavia/nordmicro.php).

It is a very small hardware synth and a joy to play and program.

I found it very easy to use as the virtual patching is similar to a hardware modular synth.
After a very short time I had twenty patches most of them self playing but many made to be used with a midi controller, in my case I use the excellent FaderFox UC3 http://www.faderfox.de/uc3.html.

It is really a shame that this synth is not in production any more and I thank Richard Scott (www.richard-scott.net) for recommending me it.

The Micro and the small Make Noise modular are going to be the core elements of my performances this somer in Europe and here in South East Asia.
They make a very powerful package and can fit in a small bag.

I wish you all a nice day here from Yangon

Malekko Richter Dual Borg Filter In the Flesh

Details via Malekko where you'll find additional samples, manuals & order info.

"The Malekko Richter series in Eurorack modular format, offer the same great sound, ergonomics, musicality, and quality that made the Wiard 300 series legendary, at a fraction of the cost and size.
The Dual Borg contains one Borg I (left side) and one Borg II (right side). The Borg is a versatile audio processor. The concept comes from a marriage of two divergent influences, the Buchla 292 Low Pass Gate and the Korg MS20 filter.
The Borg is different from most filters in that, at its heart, is a vactrol. Vactrols are combination light sensor/light resistors that possess interesting sonic traits. Often described as “rubbery” or smooth in quailty, vactrols are also know for their relatively slow response. This response creates a natural, very musical decay. In Low Pass Gate (LPG) mode, the Borg will act as a filter and a VCA simultaneously. In combination with the characteristic vactrol response, this creates a signature sound that is desired by many synth enthusiasts, especially when used with very short, percussive patches.

But the Borg is no one-trick pony, and LPGs are not for every patch. When the resonance knob is turned “on” with a click, the Borg becomes a 12db filter with loads of personality. Gorgeous resonance, influenced by the MS20 and shaped by the vactrol design swells from subtle warmth, to a roaring howl that is unique to the Borg!

A continuously adjustable low pass to high pass control is provided (a notch filter is a mix of these two). There are two audio inputs, and two CV frequency inputs (one with attenuation). Two outputs are provided, output 2 has a slightly more aggressive resonance. Removing a jumper on the back of the Borg makes the resonance “scream” even more!

The Borg I (left side) has a slower response and a more mellow sound compared to the Borg II (right side). Thanks to its longer decay time, the Borg I is best for recreating the famous Buchla bongo patch, and the Borg II is best for a faster, more aggressive response.

The signal path of the Dual Borg is selectable: Series or Parallel.

In Series mode, when you plug into either in 1, or in 2, or even both inputs (as a mix), the signal is routed through the Borg I then the Borg II filter and both out 1 and out 2 have the same signal.

In Parallel mode, a single input into in 1 or in 2 is routed through both filters side by side, and a single output (either out 1 or out 2) will give you a mix of both filters. If you have only one input but two outputs, out 1 is the Borg I filter only and out 2 is Borg II only. If you have two inputs and two outputs, then each filter is completely separate: in 1 and out 1 is Borg I, in 2 and out 2 is Borg II.

The Borg is 16hp wide, 25mm deep, and consumes approximately 80mA power.
THE DUAL BORG FILTER IS DUE TO SHIP APPROXIMATELY APRIL 25TH."

Euclid's Gear Box

Published on Apr 30, 2013 davidryle·108 videos

"A quick patch project based on some Euclidean Rhythm ideas recently discussed on the Muffwiggler's Forum. Since I don't own a single module like the COTK C969 Eclidean Bi-Clock Sequencer, I decided to rig up my modular to impersonate the general idea.

Patch details include...
The kick drum, snare and bass line are using variations on 16 beat patterns. The other two elements are 12 beat with 2 fills and 11 beats with 4 fills respectively.

The patterns are as follows...

kick = 16 beat 7 fill
snare = 16 beat 6 fill
bass = 16 beat 4 fill
RM voice = 12 beat 2 fill
second voice = 11 beat 4 fill

The 20Objects.com Ardcore 001 & Ox are handling the 16 beat patterns with the AC14 Gate Sequence sketch.
The Synthesizers.com Q960 Sequential Controller is generating the main clock and the 12 beat pattern with 2 rows of six beats and the first beat output.
The Q119 Sequential Controller is handling the 11 beat pattern by using the voltage output as a gate.
The STG Soundlabs VMS is sending pitch voltages to the 12 beat pattern's VCO's (ring modulated voice).

The Sputnik WCRS is generating quantized random pitch voltages to the 11 beat voice.
All pitch voltages are quantized through the dual Q171 quantizers from synthesizers.com.
The bass line pitch voltage is using a slow square wave LFO through a Q125 signal processor and a channel of a Q171 quantizer for a shifting 2 pitch pattern.
The kick drum is a Polivoks Filter resonance. The snare is white noise through an Oakley Diode Ladder Steep and mixed with the enveloped white noise then a touch of room reverb from a Strymon Blue Sky reverb.

The patterns were first realized using Wouter Hisschemöller's "Euclidean Rhythms Generator" java script. See: www hisschemoller dot com for further info."

"A 3 stage sequential sample and hold!

The CGS734 is an analog control voltage shift register, three stages in length. It duplicates the functionality of the Serge ASR, but goes about it in a very different way. An Analog Shift Register is a sequential sample and hold module for producing arabesque-like forms in musical space. Whenever pulsed, the previously held voltage is sent down the line to three consecutive outputs to produce the electrical equivalent of a canonic musical structure. It is great for producing sequences for VCOs, but is also useful for many other CV applications.

Unlike ASRs produced using "bucket brigade" techniques, the CV outputs are constant from the beginning of the cycle to the end - there is no "charge period" in which a brief glide is heard.

Perfect Circuit Audio (RSS)

"The CGS758 Utility LFO is a dual utility LFO offering manually variable wave shapes and intermixing of the two LFOs.

Standard waveshapes are falling ramp variable through triangle to rising ramp, and variable pulse width. A fixed square is also available, as is a combination waveshape that is variable between the saw/tri output and the square. This is a mix, not a morph.

The two switches, Join and Swap, allow the variable outputs of the two LFO’s to interact. The Join switch interconnects the two variable outputs by swapping their ramp outputs with each other, so that each output is a combination of that LFO's square wave with the other's ramp. The Swap switch reverses the outputs of the second LFO so that when Join is on one VARI output is a combination of both square waves while the other is a combination of both ramps. When Join is off, Swap merely reverses the direction in which the second LFO's Vari knob works.

via this auction
Perfect Circuit Audio (RSS)

"The CGS762 Slope Detector is an event-driven gate/trigger generating device.

It monitors a control voltage, and responds according to what that voltage is doing. If the voltage is rising, the slope detector gives a gate output (approx. 5V) on its "Rising" output. Likewise, if the voltage is falling, the slope detector gives a gate output on its "Falling" output. The duration of this gate signal depends on the incoming CV and the setting of the sensitivity pot. When the CV is remaining constant, the "Steady" output activates.

These gate signals can be used to fire envelope generators dependent on the action of the CV, for example opening a filter when a melody is rising in pitch, and closing it when the melody is falling in pitch. It can also be used to generate gate signals from LFOs, envelope generators, to advance sequencers etc.

The sensitivity pot allows the slope detector to work with either relatively fast events, like the edges of a square wave pulse train, or very slow events, such as the sine output of an LFO being used to drive filter/phaser sweeps.

Features

Sensitivity level knob
High/Low Sensitivity switch

Perfect Circuit Audio (RSS)

"A handy module for converting MIDI data to trigger pulses.

The ED103-MIDI2SDS(X) is an 8-channel MIDI note to Trigger unit suitable for use with a variety of drum machines including the SDS range from Simmons for which it was originally designed.

The unit has 8, velocity sensitive, trigger outputs which can be assigned to a specific MIDI Note using the `LEARN’ mode.

The period of the gate-on time can be adjusted using the onboard trimpot (P101) from approximately 1mS to approximately 130mS. Factory setting is 10mS.

The amplitude of the trigger outputs can be adjusted using two onboard trimpots. P151 sets the lower voltage level and is factory set for 0V. P152 sets the upper voltage level which can extend from around 5V to 10V. The factory setting is 5V.

It also has a 'learn' mode, which lets you assign different notes and channels to different triggers. You could, for example, have four triggers on channel 10, two more on channel 11, one on channel 15 and one on channel 2.

To use the `learn’ mode, you simply hold down the LEARN button until all the LED’s come on. Then the LED for the first channel to be set will flash once every second, indicating that it is waiting for a note to be assigned to trigger it. Once received it will trigger its output, and then flash the next LED showing it is waiting for the next trigger assignment. Repeat for all 8 triggers, if you don't want to reprogram all the outputs then simply wait, the unit will time out after roughly 4 seconds, saving any changes to trigger notes in FLASH memory.

8 LED’s indicate the status of each of the output triggers and are also used during LEARN mode to assist the user whilst programming the board.

Elby Designs ED108 ChaQuO Chaotic Signal Generator

via this auction

"A healthy dose of chaos for your eurorack modular!

The ED108-ChaQuO is a combination of a Chaos Generator (CG) and a Quadrature Oscillator (QO) and was designed by Ian Fritz.

The main function of this module is a versatile chaotic signal generator (CG). Chaotic signals are signals that have varying degrees of interesting irregularity without actually becoming random. This CG is an analog electronic simulation of the classical driven double potential-well problem, with the addition of extra gain in the circuit loop, and an extra cross-coupling path to extend the range of chaotic patterns available.

The double-well system is a "second-order" system and therefore requires an external driving signal. This is provided by the second part of the module, a sinusoidal Quadrature Oscillator (QO).

The two parts of the module may be used together or separately. The CG may be driven by any output of the built-in QO or by any external oscillator. The QO may drive the CG or be used independently as a four phase oscillator for the usual spatial modulation and other applications. Both parts of the module are manually controlled, to provide a compact, cost-effective unit. The QO has a frequency span of roughly 0.03 Hz to 3 kHz in two overlapping ranges.

This is a unique and complex module, we advise you to read the manual thoroughly to get the best grasp of how to use it.

"The Elby Designs Threshold/Gate/Trigger/Sample/Hold isn't your everyday sample and hold!

The ED109-TGTSH is a module that combines two important synthesizer functions. It produces trigger and gate signals whenever a "timing" signal input crosses a user-defined threshold. At the same time, the trigger pulse fires a high-performance sample-and-hold circuit that samples a second "main" signal input.

The timing signal waveform would, typically, be a waveform with a -5V to +5V swing. This signal can range in frequency from around 0Hz to well over 5kHz. The triangle output from a good LFO would be a good example.

Note: Auction links are affiliate links for which the site may be compensated.
via this auction
Perfect Circuit Audio (RSS)

"The ED114 4x4 AD/AR envelope generator provides a versatile alternative to other designs.

It consists of two parts: the main AD/AR envelope generator itself and an auxiliary delayed pulse generator. The pulse generator output can be used as a trigger or gate to control the main envelope circuitry, or it may be used independently as an external timing/gating signal.

The circuit has four input modes and four output signals, hence its name.

Input modes

Trigger/Gate: This is the main input. It will take just about any signal you feed it. Driven by a trigger pulse, the unit's output is an attack-decay (AD) envelope. Driven by a gate its output is an attack-release (AR) envelope. And you can even use a continuous signal like an LFO for the gate.

Cycle: A pulse is generated at the end of the envelope decay/release and can be switched back to the input to produce a repetitive AD output signal.

Manual Trigger: A momentary push button switch on the panel generates an input trigger pulse to generate an AD envelope.

Delayed Pulse: An auxiliary circuit produces a delayed, fixed-width pulse, which may be switched to drives the EG circuitry (Pulse - EG). The pulse may be initiated by any signal with a positive-going 1.5 V crossing, for example, a trigger pulse or a waveform from an LFO etc.

Output signals

AD/AR: This is the main envelope output.

EOE Trigger: A trigger pulse is generated when the envelope falls to near zero (end of envelope). This pulse may be feed back to the input to generate a cyclic signal, or may be used externally for cascading more than one unit or for other timing applications.

Delayed Pulse: The delayed pulser's output is available at the front panel, to use separately from or in conjunction with the EG itself. The delay time is retriggerable, ie if multiple triggers are received during the delay phase, the end of the delay phase is determined by the last received trigger. The pulse width phase is not retriggerable, ie a fixed pulse width always occurs.

EOP Trigger: This is a trigger pulse generated at the end of the delayed pulse (end of pulse). This pulse may used for a variety of timing functions, such as cross-coupling with the EG to generate a cyclic signal with a zero-voltage segment, for cascading more than one unit or for other external timing applications.

Elby Designs ED117 Wavolver II Waveshaper Module

Note: Auction links are affiliate links for which the site may be compensated.
via this auction
Perfect Circuit Audio (RSS)

"The ED117 produces a wide variety of evolving waveforms in response to an external control voltage.

Driven by a triangle wave, it can produce an output wave that continuously evolves from a triangle to an antisymmetric pulse waveshape. In addition, the section of the antisymmetric waveform that is at a zero-volt level can be replaced by an evolving series of successively folded triangular sections, somewhat in the spirit of the popular Serge Wave Multiplier.

The Wavolver II is a novel, versatile waveshaper that generates a special kind of double-pulse waveform along with an extra folded-wave section added between the pulses. It generates a wide range of timbres from a gentle sine or triangle wave to a very rich signal with multiple zero-crossings per cycle. The module can be driven by any continuously varying signal. For simplicity let's assume a tri wave at the input. The circuitry works by only passing the input signal when its amplitude (positive or negative) is above a threshold set by the pulse width control. When it's below the threshold the output signal is zero. The signal consists of steeple-shaped pulses that can be swept from narrow for high harmonic content to full width, which results in a triangle wave (pulse width and modulation controls). This represents a wider range of timbres than from the familiar rectangular pulse generators, which give a square waves at full width.

In addition to the double-pulse generator, the Wavolver II has circuitry to generate a series of evolving folded waves between the pulses. These are mixed into the output via the "fold mix" control. The folder output is available separately to allow individual processing of the double pulses and the folds.

The double-pulse signal consists of a positive pulse and a negative one, and the resulting signal has odd harmonics only. The capability to produce waves with strong, odd-only harmonics is practically never seen in classical vco/waveshaper designs. There is a wide area of timber space available here that has been largely ignored. Adding the folder output produces high-energy even harmonics in the signal's spectrum.

In the Wavolver II there are several ways to modify the basic waveforms discussed above. First, the amplitude of the second pulse can be continuously tuned from -5V (as shown above) to +5V (pulse 2 amplitude control). At full positive amplitude, the signal has two identical positive pulses, resulting in a signal at twice the frequency of the driving signal. Waves with the second harmonic stronger than the fundamental are musically useful, as some acoustic instruments (bowed strings) share this characteristic.

Another way to change the basic waveforms is to add a DC voltage offset to the input signal (input offset control and modulation). A positive offset makes the first pulse stronger and wider and at the same time it makes the second pulse weaker and narrower. Again this adds even harmonics into the output spectrum and results in some interesting timbres, especially when modulated.

Finally, the wave shape can be modulated by modulating the input waveform. There are many ways to do this, of course.

Elby Designs ED115 SH Noise Eurorack Module

Note: Auction links are affiliate links for which the site may be compensated.
via this auction
Perfect Circuit Audio (RSS)

"The ED115 – SH-Noise is comprised of a Noise Generator section and a Sample & Hold section in a 4HP module.

Noise Generator

White noise: This module uses the noise produced by the base-emitter junction of an NPN transistor, which is reverse-biased. The noise is amplified to a level of about 10V peak-to-peak.

Pink noise: The pink filter is a 3db/octave filter which is pretty linear across the range 10 Hz to 15 kHz to within 1db across the full 50db range. A final stage buffer-amplifier sets the output level to around 10V peak-to-peak.

Violet noise: The violet filter has two frequency dependent elements in the feedback path. The first feedback element on its own would produce a 6db/octave rise in the gain of the amplifier from 0db at 0 Hz via 3db at 9 Hz to 20db at 90 Hz. the second feedback element on its own would produce a 6db/octave fall in gain from 0hz to 1khz above which the gain would remain constant at 0db.

The combined effect of these feedback elements is that below 90 Hz the 6db/octave rise and 6db/octave fall cancel out, giving a gain of 20db. Above 90 Hz the gain falls at 6db/octave to 0db at 1 kHz, above which it remains constant. The result being that the bass end of the noise spectrum is boosted and "colored" noise is available at the violet output. A final stage buffer-amplifier sets the output level to around 10V peak-to-peak.

Random noise: The random noise output is a 12db/octave lowpass filter which passes only the very low frequency components to produce an extremely low frequency "random voltage". Fluctuations of the random voltage are displayed on an LED indicator.

By default, the random output is an analogue voltage with a nominal range of around 10V peak-to-peak. However an onboard jumper allows this output to be steered through a dual comparator to provide a digital output.

The digital-random output generates +5V output whenever the random voltage is greater than around +2V, a -5V output when the random voltage drops below -2V and a 0V output when the random voltage is within the range -2V to +2V.

Sample & Hold

"The ED116 Extended SH-Noise is the same circuit as the ED115, but adds flexibility providing manual settings for the Red/Blue content of the Violet noise source and Rate control of the Random noise source.

Noise Generator

White Noise: This module uses the noise produced by the base-emitter junction of an NPN transistor, which is reverse-biased. The noise is amplified to a level of about 10V peak-to-peak.

Pink Noise: The pink filter is a 3db/octave filter which is pretty linear across the range 10 Hz to 15 kHz to within 1db across the full 50db range. A final stage buffer-amplifier sets the output level to around 10V peak-to-peak.

Violet Noise: The violet filter has two frequency dependent elements in the feedback path. The first feedback element on its own would produce a 6db/octave rise in the gain of the amplifier from 0db at 0 Hz via 3db at 9 Hz to 20db at 90 Hz. the second feedback element on its own would produce a 6db/octave fall in gain from 0hz to 1khz above which the gain would remain constant at 0db.

The combined effect of these feedback elements is that below 90 Hz the 6db/octave rise and 6db/octave fall cancel out, giving a gain of 20db. Above 90 Hz the gain falls at 6db/octave to 0db at 1 kHz, above which it remains constant. The result being that the bass end of the noise spectrum is boosted and "colored" noise is available at the violet output. A final stage buffer-amplifier sets the output level to around 10V peak-to-peak.

Random Noise: The random noise output is a 12db/octave lowpass filter which passes only the very low frequency components to produce an extremely low frequency "random voltage". Fluctuations of the random voltage are displayed on an LED indicator.

By default, the random output is an analogue voltage with a nominal range of around 10V peak-to-peak. However an onboard jumper allows this output to be steered through a dual comparator to provide a digital output.

The digital-random output generates +5V output whenever the random voltage is greater than around +2V, a -5V output when the random voltage drops below -2V and a 0V output when the random voltage is within the range -2V to +2V.

Sample & Hold

The sample & hold section takes an instantaneous sample of the input signal and presents it to the out output. The resultant output is a "random voltage" that changes on each positive edge of the sample input.

"Make your patches evolve with chaos!

The ED120 is a multi-featured, autonomous, third-order chaos circuit with the following functions:

A third order system with a total of four nonlinear elements in the circuit path to provide a wide range of chaotic signals.

Exponential voltage control of rate (frequency) over a wide range, from creeping sub-audio rates to well up into the kHz audio range. Linear voltage control of loop damping, gain and offset. Many interesting sweep and modulation effects are enabled by these control inputs.

A Reset/Inhibit input which allows the system to be set to zero voltage at all three integration stages. This has many interesting uses. For example, the chaos path's evolution can be followed by varying the rate of a series of reset pulses. By limiting the range of an attractor's evolution, one can produce interesting and complex periodic waveforms.

Voltage outputs for all three system variables, X, Y, and Z.

"The ED102 is ideal if you want to upgrade your synthesizer by adding on other synthesizer units having different kinds of keyboard control voltage and trigger signals.

The built-in, fully adjustable log amp, anti-log amp, and trigger processor ensure complete system flexibility and compatibility between any presently voltage controlled synthesizer. In order to get the most out of your ED102, please read this owner's manual carefully before use. The ED102 Hz/V/Oct Converter is designed for the purpose of connecting V/Octave synthesizers with Hz/V synthesizers. This sophisticated signal processor greatly enhances the performance possibilities of your synthesizer.

Among presently available music synthesizers, there are two different types of control system used for the VCO (voltage controlled oscillator) and EG (envelope generator). One of these systems is used by Korg and Yamaha; the other is employed by every other synthesizer manufacturer. The ED102 provides you with a way to change the control signals of one system into the control signals used in the other system. In this way, it acts as an interface so that any two synthesizers can be used together, provided that the synthesizers are equipped with the conventional input and output jacks for control
voltage and trigger or gate signals.

CV systems

In the Hz/V system, the VCO oscillator frequency is proportional to the control voltage whilst in the V/Octave systems the oscillator frequency changes one octave for every one volt (1V) change in the control voltage. Since an increase of one octave means that the frequency is doubled, each increase of one volt in the control voltage means a doubling of VCO frequency.

The problem with the V/Octave system is that it must employ a log amp in order to double the frequency for each one volt increase in the control voltage. Log amp circuitry can, unfortunately, be very unstable because of its sensitivity to temperature changes. This causes so many problems that most professional musicians automatically assume that synthesizers always have unstable pitch. When Korg developed their first Korg synthesizer, they decided that such a circuit was entirely unsuitable for a musical instrument. So, instead they invented their own unique, patented circuit in which the keyboard voltage (which is the VCO control voltage) itself doubles for each one octave increase in pitch.

Four Sections

Log Amp: This changes a Hz/V type keyboard CV (control voltage) output into a V/Octave type of CV. Use the Log Amp to change the control signal from a Hz/V synt
hesizer into a signal you can use with a V/OCT synthesizer.

Hz/V input (0 ~ 15V)
Oct/V Output (-12V ~ +12V)
Frequency knob: Bi-polar offset of frequency
Width knob: Bi-polar control of width of the output
Antilog Amp: This changes a V/Octave type of keyboard CV output in to a Hz/V type of CV. Use this Antilog Amp when you want to control a Hz/V synthesizer, such as a Korg, by means of a unit that uses the V/OCT system.

Oct/V input (-4V ~ +4V)
Hz/V output (-12V ~ +12V)
Frequency knob: Bi-polar offset of frequency
Width knob: Bi-polar control of width of the output
Adding Amp: This can be used for mixing control voltage signals or sound signals. When not plugged into an outlet, the adding amp operates as if -5V and +5V inputs were connected to its two channels. Therefore, depending on how you set up your equipment, you can also use the adding amp as a voltage supply, or to shift a control voltage to a higher or lower value, and so forth.

Two inputs each with level knob
Mix output

Elby Designs CGS775 Serge VCS Voltage Controlled Slope Module

via this auction
Perfect Circuit Audio (RSS)

"The CGS775 Serge VCS (Voltage Controlled Slope) is an extremely versatile module capable of many useful functions.

The VCS is a unity gain voltage follower. The rising and falling slopes are independently and jointly voltage controllable over a wide range. The module provides an incedible amount of possible functions.

Slew time can be set separately for rise or fall and be modulated by a control voltage. Separate inputs for rise and fall modulation and also a common input. The modulation controls are bipolar and can be toggled between linear or non-linear behavior. A trigger on trigger input fires an envelope while a gate holds sustain. After a cycle of the envelope a gate signal is generated at the end-out. The cycle switch connects the end-out with the trigger in so the VCS can loop itself and act as an oscillator which frequency can be controlled via the Exp-CV jack. Manual control of waveform with the rise / fall controls. If an audio signal is fed into the module, the pots act as waveshape or cutoff controls.

Some possible functions:

VC Transient Envelope Generator: A pulse at the trigger input will start the envelope, or a gate input will sustain the level and the envelope will fall when the gate goes low. Rise and fall are independently and jointly voltage controllable, with variable linear and exponential wave shapes.

VC Portamento: Voltage is slewed according to the rise and fall times.

VC LFO: When the cycle switch is thrown, the trigger input is connected internally to the end trigger output, creating a VC clock with variable waveform and independent rise and fall times.

VC Oscillator: While not as wide ranged, or accurate as a dedicated oscillator module, the VCS is still an excellent audio source. The Exp CV input is scaled approximately to the 1v/oct standard. The Output wave can be swept from triangle to saw with linear and non-linear waveforms. End Out also produces a pulse waveform.

VC Non-Linear Audio Processor (Low-Pass Gate): If an audio rate signal is slewed, the module responds like a VCF, and a rough VCA. The signal is low-pass filtered down to silence, similar to a low-pass gate.

Envelope Follower: Positive and negative peak detection envelope follower.

VC Pulse Delay: Trigger input starts the envelope and a trigger will be produced again at the End Out when the envelope completes its cycle.

Sub-Harmonic Generator: If a series of triggers are applied to the VCS faster than the total rise and fall times, the module will divide the incoming signal by a whole number. In the audio range the output will be the sub-harmonic series.

Elby Designs CGS757 Bi-N-Tic Filter Module

Note: Auction links are affiliate links for which the site may be compensated.
via this auction
Perfect Circuit Audio (RSS)

"The CGS757 Bi-N-Tic Filter is a strange mixture of a VCO and a switched capacitor filter based on the filter presented by Jan Hall in Electronotes. If you are after something different, this fits the bill. After all, how many filters have a sync input?

A little on how it works:

A VCO drives a pair of analog switches, switching two banks of eight capacitors across op-amps, creating a multi-passband or comb filter at f0, f1, f2, etc. Two controls are provided within the structure of the filter - damping and bandwidth. Not all combinations of these two are actually valid, some resulting in silence, but none the less, quite an array of variations is possible.

The VCO is connected via a signal processor to the input of a binary counter, creating divisions. The first three divisions are used to drive the pair of analog switches. The remaining divider outputs are also available via the Feedback rotary switch. This is passed through a level knob and fed back into the input of the filter itself, thus giving the filter an excitation signal that is perfectly in sync with its operating frequency. This causes the filter to become a very unusual oscillator, giving quite complex waveforms or even simple waveform sequences (ringing bursts). There is also an "Excite" input for using external signals to excite the filter, select X on the Feedback switch to engage it.

Elby Designs CGS738 Mangler Saw Pitch Shifter Module

Perfect Circuit Audio (RSS)

"The CGS738 Mangler is a euro-version of the CGS38 saw pitch shifter from Ken Stone. It is a combination of op-amp summers and comparators with surprising results, ranging from complex wave shaping to pitch shifting of saw tooth waves.

Some ideas on how to use this module:

As a waveform mangler: Feed it any combination of waveforms, or a waveform and a control voltage and adjust as needed. For example, feed a waveform from a VCO or LFO into one input, and adjust the input level for differing effects. Use a control voltage as an offset signal to introduce variation. This can be from an envelope generator, keyboard or LFO or another VCO.

As a sawtooth frequency doubler: Feed in a single sawtooth wave, and adjust the associated gain. When the gain reaches 2, assuming a 0 to 5 volt waveform, the result will be a sawtooth of twice the frequency at the first output.

As a sawtooth pitch shifter: Feed an audio frequency sawtooth wave into one input, and a sawtooth wave from an LFO into the other. Disable one input using the switch, then adjust the input level of the other input until the LED lights, and then back off until it goes out. Disable the other input using the switch, then repeat the procedure for the other input. Return the switch to the center position. The LED will now work as a "signal present" indicator and can be ignored. One output will be the sum of the two frequencies, and the other should be the difference, depending on the relative slopes of the two sawtooth signals. If the result sounds rough, tweak one of the inputs until it sounds clean.

Note that getting the pitch shift to work correctly takes some experimenting and tweaking. The input waveforms should be in the range of 0 to 5 volts - specifically with the bottom of the waveforms actually hitting 0 volts. An external offset may need to be mixed in if this cannot be achieved. The downward shift output is very sensitive to gains and offsets, and is unlikely to be as pure as the upward shift output. If you want a more accurate downward shift, swap the direction of one of the input waves, and upward shift output will act as a downward shift output and vice versa. Some very powerful sound can result, even with impurities in the shifting, especially when the incoming frequency, and the up and down outputs are mixed together.

Also note that this is NOT a frequency shifter, the relationship between the harmonics are preserved.

Elby Designs CGS747 Cynare Drum Simulator Module

Note: Auction links are affiliate links for which the site may be compensated.
via this auction
See Perfect Circuit Audio (RSS) for more.

"The CGS747 Cynare Drum Simulator is a euro version of the third in the series of CGS drum simulators. It generates a single drum sound that can be adjusted to sound like a cymbal, hi-hat, snare drum, electronic drum, or numerous other percussive sounds. It is a complete dedicated synthesizer in its own right, including six oscillators, a noise source, a mixer, an envelope generator, a VCF and a VCA.

Some ideas on how to use this module:

There are two inputs for controlling the envelope of the generated sound. The first is Decay. Attack is preset at the fastest rate possible, the decay controlling the fall off rate of the envelope. This decay is also affected by the Damper control, which operates in parallel with the Decay. A gate input into the Sustain jack disables the damper, thus allowing two different rates of decay to be set depending on the input to the sustain jack. Note: if the damper decay rate is set to minimum, and the sustain input is below about 2V, the envelope will be set at minimum, with the decay control having very little effect, so if you do not wish to use the sustain input, the damper decay rate should be turned to maximum.

If a square wave or similar gate waveform is connected to both the sustain and trigger inputs, the fall-off of the envelope will be affected by the decay control while the gate signal remains high, the damper kicking in as soon as the gate falls low. This allows for easy implementation of open/closed hi-hat sounds etc.

A little on how it works:

Incoming trigger and sustain signals trigger the onboard envelope. If the sustain gate signal is low, the envelope is run through the damper section. Otherwise, if the sustain gate signal is high, the envelope is only controlled by the decay knob. An LED indicates whether or not the damper is active.

The envelope is also passed through a processor that allows it to be scaled and inverted via the bi-polar envelope knob, giving a range of positive and negative envelopes to drive the VCF.

There are two noise generators, a conventional one, and a "shimmer" generator consisting of six independent oscillators with their outputs "ring" modulated via the exclusive OR gates, and mixed.

A knob allows the ratio of noise to shimmer to be adjusted. A filtered version of the trigger pulse is used to generate an impact sound, and this is mixed with the output of the shimmer/noise section.

The filter section is directly taken from the Steiner VCF.

See Perfect Circuit Audio (RSS) for more.

"The CGS735 Synthacon Filter is a "tribute" module, based on the awesome Steiner-Parker Synth VCF.

Unlike most multimode filters, which have a single input and seperate mode (LP/HP/BP) outputs, this filter has an input for each mode and a single output. This gives the filter a ton of character and allows for a lot of interesting effects. Resonance is a bit unusual in its behavior. Once it starts oscillating, the resonance pot needs to be backed off a fair way to get it to stop again. It can also be frequency dependent.

This module includes an input mixer. Each of the filter type inputs has its own level control. The ALL input is also affected by these level pots as it is mixed with the individual inputs prior to the level controls. If using only a single input, it may be better to feed the signal into the ALL input, and adjust the level pots to select LP, BP or HP, rather than changing the patch cord between the specific input jacks.

If the same signal is used in all inputs, the result is reminiscent of a phaser. The real fun starts when you feed different signals into each input, then you get a frequency based "interpolating scanner", where sweeping between different sound sources is possible, though also subject to the frequency at which they are running.

"Fully refurbished Roland TR-707 drum machine, with a twist! Added pitch controls and a circuit bending patchbay allow for tons of expirimentation and unique sounds. Disengage the modifications to use it as a classic stock 707, or engage the pitch controls and start plugging in the circuit bending patch cables to explore it's awesome new sonic capabilites.

Pitch Controls

10 by-passable pitch controls have been added, which affect individual sounds or groups corresponding with the volume faders. Each pitch adjustment has a by-pass toggle switch, pitch control, and status LED. This modification works by manipulating the clock frequency of the affected sounds playback. In bypass mode the original clock frequency is received and the original 707 sound is produced. When the pitch adjustment is activated the original clock frequency is replaced by the added external and adjustable clock frequency generators. Pitch ranges from way above to WAY WAY below original clock/pitch.

Circuit Bending Patchbay

In addition to pitch controls, the modification includes a 10 point ROM-based bending interface aka circuit-bending patchbay. Linking these points with patch cables accesses a mixed bag of odd effects, filter, modulated, and otherwise unique sounds. These effects are the result of cross-modulated and otherwise scrambled ROM data being converted to audio. When none of the modifications are engaged these machines will function and sound as Roland intended. Modification only affect audio and all other functions remain functional no matter what mode or modifications are engaged.

Fully Refurbished

In addition to the insanely fun modifications, all units are fully refurbished. All Diabolical Devices TR-707's are completely disassembled and cleaned: the panel/button board, all key contacts, switching outputs, and all faders and cleaned and treated. The DC power input is replaced and the circuit board is treated to prevent future failure (common weak spot). All interface jacks (MIDI, audio in/puts, and sync) are resoldered and inspected.

Frequently Asked Questions

jb?

Gieskes sells a version called the HSS3j. The HSSjb adds glitch switches, the “stable” mode which makes the output solid blocks of color rather than lines, as well as an enclosure.

What does the midi input control?

You can control some variables of the HSS3i over midi. See the user guide for the implementation chart.

What does the audio input do? Is this thing an effect? Can I run my guitar through it?

It’s not an effect but it does allow you to hook up an audio source to trigger off of. The audio input works best with rhythmic sources, but all kinds of sources can create interesting effects. The list of what the inputs do in different modes is in the user guide.

Can the HSS3jb do everything the HSS3i could?
