"dual/stereo mmf filter & vca"


Published on Dec 28, 2019 Robotopsy Robotopsy

"Some tips for the ODLPG from Cavisynth."

"This module was designed and assembled in Switzerland by hand and with love.

“ODLPG” = Opto – Disto – Low – Pass – Gate

ODLPG is a lowpass gate whose circuit is based on the diversion of an optocoupler usually used to electrically isolate two circuits.

In other words: it is a vactrol that controls the opening of the VCA and the filter at the same time, giving a particular roundness to the sound.

In addition, this circuit architecture extremely simple, adds a little distortion when the CV that comes from your EG is quite strong.

The “curve / drive” knob increases the opening of the filter and the (light) saturation value at the same time.

The panel is matte black (like the Bufflide)

Technical specifications:

Format – Eurorack
Power consumption – 10mA [-12V] // 10mA [+12V]
Module width – 4HP (20mm)
Module depth – 12mm (Skiff super friendly)
Weight – 35g"

New Mini Roland System 700 LAB Eurorack Clone by OMNiSYN

[000] OMNiSYN System 700 LAB Demo Published on Dec 21, 2019

"Clone of the Roland System 700 LAB"

This one was sent in by John L Rice.

OMNiSYN is a new maker as well. No additional info at the moment. It does look appear to be 3U eurorack of course.

You can spot three 702F oscillator modules on the far left for each row. A 703M Filter on the top and bottom rows, 705B dual ADSR envelop in the middle row, a Mixer in the middle row, and a few other modules.

Update via OMNiSYN in the comments:

"All modules (bar the 717 sequencer) are prototyped - prices would be comparable to to other manufacturers, but these are all dependent on availability of parts (some are custom and long lead time). Some videos on the full Roland System 700 clone are coming soon - stay tuned."

"All modules are 3U/12HP or 3U/18HP, case is 9U/60HP with 1A PSU and expansion port built in. All signals are brought to the front panels as was true in some of the original modules. Some modules have been expanded as in the mixer is now 2x 3 input and most modules use NOS original components. Hope this helps."

The original Roland System 700 Lab came with the following so this seems to match: 3 VCOs, 1 VCF, 1 VCA, 1 LFO, 2 ADSR EG, Noise (white & pink), Ring Mod, S/H and a Mixer.

Below is an image of one from the RL Music website. Apparently the signal path was normalized so you could play it minus cables like an ARP 2600. I'm guessing the OMNiSYN eurorack version consists of independent modules and is not normalized.

"This is a very powerful 3 oscillator normalised system with 1/4 inch jack In/Out for expanded sound creation possibilities and is based entirely on the system architecture of the full System 700."

Soundforce Dual Filter // "affordable" dual LP or HP OTA based filter in Eurorack

Published on Dec 21, 2019 DivKidVideo

Available at Signal Sounds for £129.00.

"Here we have the new Dual Filter Eurorack module from Soundforce. It’s an OTA based design that has it’s routes in the later updated Korg MS-20 filter cores. The Dual Filter is a dual independent mono filter where each of the filters can be set to low pass or high pass filter modes with jumpers on the back of the module. Patching one side into the other we can make HP-LP series processing chains, patch in dual mono, stereo or parallel processing and we can also make band pass filters by using both sides.

"The SoundForce Dual Filter is a 2-stage cascaded OTA design based on the late MS-20. The design has been fine-tuned with extended resonance control as well as a resonance CV input. Each filter can be either a 12dB/oct low-pass or 6dB/oct high-pass. To keep the module HPs on the low side, the filter mode setting is located on the back of the module. The module was designed to be a very affordable full-featured modern filter.

Highly efficient design:
This design attracted me very particularly due to its beautiful simplicity. With only 2 poles, it uses a total of 3 OTA ICs and 4 OP-AMP ICs for both filters even with the added resonance voltage control. Early on, efficiency and part counts were a focus during testing and development. In combination with automated manufacturing and a very short supply chain, the module has a very high quality standard at a very affordable price. The module uses only A-brand ICs and passive and no costs were cut during purchasing."

Published on Dec 19, 2019 synthprocess Club of the Knobs Synthesizer

"Club Of The Knobs Modular Analog Synthesizer manufactory now offers the SEQUENCER COMPLEMENT B. In contrast to the original, the interface 961 has been replaced against two CP958 Dual Scale Programmer. Thus not only the output of the sequencers can be quantized but using one channel of the CP958 in keyboard-mode allows to transpose the sequences without additional external devices. Wishing you a happy new decade - and celebrate the sequences!"

The Sequencer Complement B was an original Moog Design. You can find some posts featuring the Complement B here.

In contrast to the original Sequencer Complement B, we have exchanged the Interface 961 against two of our CP958 Dual Scale Programmer. This offers the advantage that not only the outputs of the C960 Sequencers can be quantized, it is even possible to use one channel of the CP958 in keyboard mode to transpose the sequences without additional external devices. New in our range is the (original) CP962 Sequential Switch.

Announcement NEW DIVKID EURORACK MODULE // Meet ochd made with Instruo

Published on Dec 18, 2019 DivKidVideo

"Hello hello, here's my second eurorack module øchd or ochd. It's pronounced "oct" as in octave or octuplet and as if by magic there's eight outputs on this module, an octuplet of analogue LFOs if you will. I often find I need more modulation, simple sources that will keep things moving and stop things getting repetitive. That’s why ochd was brought to life, to keep patches organically drifting and moving… and as it’s modular, we wanted an intuitive easy to use module with plenty of patchable tricks up it’s sleeves too!

ochd is a 4HP Eurorack module with eight analogue triangle LFOs. The outputs go from fast on the top output to slow on the bottom output. The default ranges are deliberate NOT synced. These are free running LFOs that were tuned by ear to be musical useful for a range of fast to slow modulations in a patch. Organic animation, drifting and musical phasing is the intention of the module. The rate control controls the rate of all LFOs globally and takes this into lower audio rates right down to 25 minute cycles on the lowest output. This can be extended even slower with CV, with the CV input and attenuverter on board and we can also track and hold the outputs with a negative CV, interrupting and holding modulation values with external gates of CVs. Another trick to take this from simple triangle shapes is to patch a spare output into the CV input and wave shape with feedback. Exponential curves, odd squares, stepped waveforms and more are available with some adjustment of the attenuverter and using different outputs to voltage control itself.

While patching a prototype at DivKid HQ Richard Devine said this was "the most organic little modulator ever" - lovely stuff!"

"I finally 'finished' my custom synth SimpleSynth.

SimpleSynth is a Teensy based synth with the main objective to keep it simple (code wise and hardware wise).

Timestamps at the bottom!

In this demo I was sending MIDI notes via USB to the synth and I recorded the audio raw coming also through USB.

- FM, AM and Ring synthesis with 1 carier and 1 modulator
- Polyphonic synth, Arpeggiator and Drone modes
- Controllable modulator gain and frequency
- Controllable Attack, Decay, Release
- MIDI over USB
- MIDI through the Hobbytronics USB Host Board Controller

ST Modular - Rocinante´s Gate

Published on Dec 16, 2019 Stefan Tretau

"LPG with Envelope Generator and LFO

Rocinante´s Gate is not a classical low-pass gate (LPG) using vactrols, but goes way beyond that providing an adjustable envelope to control the "gate" through an analog filter. Sending a gate or trigger signal into the GATE INPUT will create these envelope shaped sounds you know from other LPGs.

The LOWPASS knob adjusts the range of frequencies being affected by the gate. If you turn it fully counter clockwise the whole frequency spectrum will be gated. Turning it clockwise will slowly add low frequencies to the gated singal until the whole spectrum is not affected anymore.

ENV AMT sets the amount of how much the internal envelope affects the low-pass gate. RISE sets the time how long it will take the sound to go from silent to the loudest level. Just like the time it takes the LED insight of a vactrol to start lighting to its full potential. DECAY controls how long it takes to go from an intial peak to the "gate-phase" level. The length of this phase is varied by the LENGTH potentiometer. Finally FALL changes the time your sound will need to return to silence after the "gate-phase". Just like the time it takes the LED insight of a vactrol to shut down.
RESONANCE sets the amount of filtered audio being fed back into the filter input. It can´t go into self-oscillation, but is able to create very crunchy and juicy overtones when turning clockwise.

The internal Trigger Generator is being controlled with TRIG RATE and the RE-TRIG/LOOP SWITCH. Adjust the rate of the trigger and apply the singal to either a re-trigger circuitry that repeats the "gate-phase" as long as a gate signal is being applied or to a loop functionality that will create cycles of gates without an external gate or trigger. The ENV/INV SWITCH enables you to alternatively route an inverted envelope to the low-pass filter. This way you may create "ducking" or "side-chained" sounds.

An internal triangle LFO can be routed via the LVL ATT attenuator to vary the amount of envelope that is being passed to the gate. The LFO will be deactivated if you turn the LVL ATT attenuator fully counter-clockwise or if you use an external signal to control the envelope amount by patching a CV signal into LVL CV.

In addition to the Audio IN and OUT jacks you may take the signals of the internal envelope and LFO from the ENV OUT and LFO OUT to controll external devices. In combination with the loop function Rocinante´s Gate is not only a Low-Pass-Gate, but also an LFO and ADSR Generator.

New intellijel Tete Expander for the Tetrapad

Published on Dec 11, 2019 Intellijel

"Tête is the long awaited and highly anticipated expander for the Tetrapad. Tête takes control of Tetrapad’s mode selection and operating functions, allowing Tetrapad to do what it does best — act as a control surface, which it does both for controlling external modules and for interfacing with the advanced processing power within Tête.

Tête + Tetrapad operates in one of three different modes—

Up to 16 voltage storage locations (grid) with 8 voltages stored at each location. You have the choice to record and playback your recall of these locations in a looper style (just play freely and spend arbitrary amount of time at any location) or as a clocked sequence (SH-101 style). Additionally you can traverse the matrix using the X and Y CV inputs to get Cartesian style sequencing. There is also variable slew that allows you to morph/glide between the values.

You can create sequences or loops in chord, scales or keyboard mode. The isomorphic keyboard grid can be set to 4, 12, or 16 notes. There are real-time performance looping, transposition and inversion capabilities via the CV inputs and dedicated loop button. In sequencer mode each step can be a tie, rest, or gate with size 25/50/75%. Basically we have created a way to very quickly and intuitively make chord sequences that are very musical and easy to manipulate. It is difficult to summarize in words but we will be sure to create some videos to demonstrate how easy and fun this is to play with. It definitely represents something unique in the landscape of Eurorack sequencers.

In this mode you can loop record your performance on any combination of the following functions: fader, bipolar fader, crossfader, euclidean sequencer, toggle switches or LFO. Kind of like Elektron style parameter locking but all of the motions is recorded continuously instead of just in slices. Instantly turn a simple patch into a highly animated and complex beast. The chosen function determines the type of signal (CV, note, trigger, gate, etc.) sent from each of Tetrapad’s eight independent outputs, while its multitude of multi-colored LEDs keep you informed of exactly what’s happening within each mode."

New ADDAC ADDAC216 Sum & Difference Eurorack Module

via ADDAC System

"There are two equal sections in this module labeled A and B.

This module is a peculiar type of mixer that instead of just summing two input signals (X & Y) it also allows the possibility to subtract the two signals.
It works both for audio and CV signals and hence the possibility to get the diference of two CVs or cancel the phase of two audio signals. The resulting signal, of sum or subtraction, is then routed through a switchable (on/off) full rectification circuit labeled: Absolute. After this the gain of the mixed signal goes through another attenuverter labeled: Amplitude to control the resulting signal gain which, being an attenuverter, also allows the possibility to invert the incoming signal. After the Amplitude comes an AC/DC coupling switch followed by an bipolar Offset knob.

Besides the normal output there’s also an inverted output for each of the A & B sections.
The outputs of section A & B are also summed and sent to the Average Output.

Using a single input, just the X or Y input, the module can also be used as a simple dual Attenuverter & Offset CV processor with full rectification and AC coupling options.


2 independent sections each with:
2 inputs with gain attenuverters
Amplitude attenuverter and bipolar Offset
Absolute/Bipolar and AC/DC switches
Output and inverted output
2 leds monitor the Output polarities and gain.

Average mix output of both sections"

Exploring The Baal 3080 VCF

Published on Dec 7, 2019 John L Rice

"The Baal 3080 VCF

0:00 - Beginning/Title Card

4:18 - Bandpass Tests
6:07 - Tracking Test
6:43 - Patch Test With Rhythmic Modulation
8:54 - Party At Baal's Place
11:22 - End

Most of the gear used is explained throughout the video but since the special music video Party At Baal's Place is more involved, here are some details:
The same patch that was at the soundtrack for the introduction of this demo is the same one that plays throughout the Party At Baal's Place music video. I used a Moon Modular 569 sequencer to control the MOTM-300 VCO pitch and to also control Baal's frequency cutoff, in addition to manually playing with the frequency cutoff and resonance knobs. Strymon Timeline and BigSky pedals were used as well as a Lexicon MX-400, all for reverb and delay.

Things were very simple, just what you hear on the introduction, until I thought, "hey, I could put a drum beat to this" . . . and from that point on it was days of "just one more quick little addition?"! (insert emoticons of a face-plant and burning banana! ;-) And there was no initial click track so . . . . .

All the drum-set parts come from a Roland Integra7 played from a A-49 keyboard, because it was the middle of the night and I wasn't setup to record acoustic drums anyways. The china/trash ride cymbal was recorded first, then the snare and bass drums in another pass, and crash/splash cymbals were added on a third pass. I dropped those into tracks and spent days cursing my sloppiness as I kept trying to tweak the timings. Some of the fills were actually created in the DAW by chopping up simpler parts and recombining them.

Next I started coming up with the lead/melody synth parts. The patch was almost all Synth Tech MOTM modules except for a Moon 526 mixer the Baal 3080 VCF of course. (2 x MOTM-300 VCOs, OTM-800 EG, MOTM-1800 EG, MOTM-190 VCA, MOTM-380 LFO, MOTM-650 MIDI to CV) I'm proud to say I played all of those parts by hand, even the fast parts, but it did take a lot of practice. The next day I started wishing I had used some distortion so I replayed it again through a Retro Mechanical Labs Electron Fuzz pedal and JHS Firefly fuzz pedal in series.

The rest of the parts were quick and easy. The choir voices are from a Mellotron M4000D rack (male chorus and boys choir combined). The chime is an actual acoustic Musser brand chime just recorded with a handheld flash recorder. And that's my voice at the very end. ;-)

Then came the video editing. I spent a while searching for clips that might go well and I eventually developed a sort of "midnight party at Baal's place" sort of story for fun. ;-)

OK, thanks for watching, ratings, commenting and for reading this long description! If you've found this and/or my other videos useful or entertaining, please consider tipping me a few bucks?"

"At its core, this is the CA3080 OTA based filter that was in the Original Rev-A version of the Octave Cat, before they switched to The SSM2040. It has been adjusted for modular level. The expo-Converter uses super-matched 3906’s and is temperature Compensated For upwards of 5-octave tracking.

Additionally, there is a 4-pole output, as well as a 1-pole output. These outputs are inverted from each other, so they can be mixed Together for Bandpass.
