Serge GTS eurorack - 1V/Octave demo

video upload by Serge Modular | Random*Source

"The Serge GTS is a complete redesign of the famous Serge Dual Universal Slope Generator (DUSG) by Serge himself - with a new core, optimized for speed and tracking. Like some of the clones it can be used for CV, but provides exceptional audio performance: transient rise times as fast as 12µs and a maximum cycle speed of 28kHz.

In this demo 2 GTS are used parallel as Sawtooth oscillators (= 4 oscillators), controlled via 1V/Oct and Midi / keyboard. In such Sawtooth mode, the GTS tracks over about 6 octaves, up to more than 2kHz."

EXTREMELY RARE PPG 1002 for Tom + first ever shop tour!!!

video upload by foleytronics fx repair

"Here is a demo of the EXTREMELY RARE PPG 1002 for Tom. Plus a bonus first ever tour of the Foleytronics shop!!

For those that want to attempt to tune this synth, here is what worked for me:

The trimmer by the regulators is the CV offset; trim for 0v for the lowest key. This interacts with the CV v/oct, which is right above where the two shielded cables connect from the 20-pin keyboard connector. Trim this for 1v/oct, which can be measured at the switched oscillator CV input jack on the back of the instrument. Once these are set, you can move on.

The oscillators are tricky. They each have an initial frequency trim pot and a volt/octave trim pot. However, the initial frequency trimmer cannot be set willy nilly to A440 because their initial tuning frequency greatly affects the octave selection switches on the top panel. What I found to be most effective is to set the MASTER TUNE front panel pot to 0, the OCTAVE SLIDER to the left of the keyboard to the middle and then begin tuning. Note, every trim pot for each oscillator will affect the others for that oscillator so this is an exercise in extreme patience.

First, turn off keyboard control for OSC B and roughly center its front panel tuning pot; set its octave to +3 and put a folded piece of paper on middle C. You are now going to tune the octave selector for OSC A; this part is confusing as there is a trimmer to adjust the octave selection offset for BOTH oscillators, but only OSC B has an adjustment to “match” its octave selection with that of A. Thus, you have to use that trimmer to get OSC A perfect and then match B to A - the method that worked for me was to switch between octaves for OSC A and adjust the octave offset trimmer along with the initial frequency trim pot for A to get a perfect octave selection for OSC A over the OSC B drone.

After the OSC A octave adjustment, it’s time to adjust B’s octave adjustment. Set A to +3, and switch OSC B to +1; adjust for zero beating at the trimmer in the upper left corner of the board right at the edge of the PCB. Then, switch OSC B back to +3 and adjust its initial frequency for zero beating; repeat this until the octave selection is perfect for B.

Now, it’s time to adjust for V/octave for each oscillator. Sadly, this adjustment affects the octave center calibration we just did, so you’ll have to keep backtracking until it’s good. Adjust the V/octave trim pot for OSC A, which is directly to the left of the CV v/octave we did in the first step. You’ll now have to mess with the init. frequency for A along with the V/oct to get the oscillator to track correctly on the keyboard, but like I said earlier, you have now probably slightly messed up the octave selection so you will have to go back and do that again. Then, adjust the tuning of OSC A again and repeat this process until OSC A tracks perfectly and has good octave selection. I couldn’t really get the +4 octave to be perfect, but hey, it’s a prototype and is probably 50+ years old.

Now for OSC B; it’s very similar to A. Use the V/octave adjustment trimmer which is the lower left trim pot on the PCB along with the initial frequency trim pot to get B to track along the keyboard. Again, you’ll have to go back and adjust the octave selection, but that’s not as bad for B because its octave adjustment doesn’t mess up OSC A’s octave selection. At this point, you should be able to get OSC A and OSC B to track the keyboard and the octave selections should be there"

Per-step Pitch Intervals with a Sequencer using PRECISION VOLTAGES module for Eurorack

video upload by AJH Synth Official

"Using a step sequencer to change VCO pitch per step: The Precision Voltages is a convenient way to offset VCO frequencies musically, by pitch increments of semitones and octaves, which can be either added to, or subtracted from an incoming CV signal, such as a sequencer or keyboard controller. This can have many uses, not just for melodic control of oscillators, but here is a particularly useful function for pattern-based pitch sequencing.
Modules connected to the outputs of the Precision Voltages will be sent fixed voltages of preset musical intervals, based on the 1V/Oct scale. These voltages, here represented as precise intervals of semitones and octaves, are selected by the two rotary switches. With no external CV signal connected to the inputs, the module will function as a source of preset fixed voltages, with a huge range of +11 volts to -11 volts (10 octaves + 12 semitones). These can be conveniently switched on or off with the A & B switches. When an incoming CV signal is present, this voltage sources is added to, or subtracted from the signal, meaning it can be used to easily shift the pitch, frequency, or CV level of modules it is connected to. This is ideal for shifting the pitch of VCO's to create harmonies or simple chords, or for offsetting CV levels in any application that uses them.
The Gate input of this module affects the value of A only, and will allow it to be turned on with a high gate signal, or off when the gate is low. B will remain unaffected, and will continue to output the pitch/voltage offset selected by the rotary pots and switches. The 'OUT' output will combine both A and B, depending on the switch position next to it. As a result, when A is turned off, either by the switch or a gate signal, then only the value of B will be output here.
Official website page: https://ajhsynth.com/Precision.html

I'm also using the new Chance Delay module on this patch for some generative randomness/probability - it's not necessary, the sequencer can be connected directly to the Precision Voltages Gate input.

SEQUENCER ADVICE: Most sequencers will allow you to change gate length, sometimes referred to as 'duty', as is done in this video, but you'll need to consult your sequencer's documentation if you are not familiar with how to do this. On many it is obvious, but others not so much. Also, some will allow you to change the gate length directly and quite precisely, whilst others will only allow you to change it in fractions or percentages. This may mean that you can't quite get the gate to span the entire step length, meaning that the pitch modification made by the Precision Voltages may be heard ending prematurely. This is the behaviour of the sequencer, not the module. However, there is a way around this...
A gate signal is just a voltage of either zero volts (off/gate is low), or a minimum of +5 volts (on/gate is high). Gates are pulse (square) waves for this reason, as they are simply one of these two states, and so some sequencers will also refer to gate length as 'pulse width'.
However, all the gate input needs is one of these two voltage values to turn it on or off. This means the CV outputs of a sequencer can also be used, so long as your sequencer has a range of at least zero to +5 volts, which they almost certainly will. Therefore if you connect the CV output of the sequencer to the Gate input of the precision voltages, set all of the step pitches (or pots such as on the SQ1 used here) to zero, when you run the sequencer the pitch changes set by the Precision Voltages will not be activated. If you then raise the pitch of a step to maximum, it will activate the pitch change on that step. Problem solved!
This is not as immediate or convenient as being able to switch the changes on or off with buttons, but it works just the same otherwise, and may be helpful if you can't get satisfactory results with your sequencer, or are finding it too difficult to adjust the gate lengths accurately.

Xaoc Devices strikes back with Batumi II

Update via Xaoc Devices: "Unfortunately, we had made an error in the Batumi II description you received suggesting the assign waveform selection was performed on a per-channel basis even without the Poti II expander. That is not the case."

Updated press release follows:

Xaoc Devices presents Batumi II – a greatly improved and enhanced new iteration of the modern day classic that is/was the original Batumi, preserving its layout and form factor. The premise remains the same: four LFO’s with individual outputs for sine, assign and rectangle waves. The channels can operate independently or they can be linked – phase shifted, divided or multiplied (new mode alert) with regard to the first channel. Multiple major and minor improvements have been implemented, e.g. when synced to an external clock source, each channel’s frequency slider selects a clock division for that channel’s outputs.

We have managed to incorporate the features of the original expander into Batumi II (sync mode switching and assign waveform selection) without changing the size of the module which opened up new possibilities for the new optional expander. The Poti II expander for Batumi II adds multi destination inputs for sine wavefolding, assign output waveform selection or rectangle pulse modulation with the destination set for each channel independently. Poti II also features frequency input attenuation as well as sine and assign output attenuation. All adjustments may be performed separately for each individual channel or for all channels simultaneously.

The Batumi II software has been rewritten from scratch to ensure best performance. The hardware has also been updated to allow for V/oct tracking and stable operation up to audio rates (more powerful CPU, precise, wideband converters, antialiased waveforms).


Batumi II notable features:

– 4 LFO’s
– redesigned from scratch – both the hardware and software
– new waveforms for the assign output (including random)
– new frequency multiplication mode
– all features of the Poti expander incorporated into the main module
– very wide frequency range well into audio rate
– 1V/oct tracking = so can be used as 4 VCO’s
– in the Phase/Divide/Mult modes the random waves at the ASGN output follow the values available in the master/A channel
– 10HP
– +90/-50mA


PRICE: 330 EUR MSRP

Poti II expander notable features:
– per-channel input and output attenuation for the SINE and ASSGN outputs
– per-channel shape modulation with switchable destination (wave folding, shape switching, PWM)
– stores settings during a power cycle
– LED indication of the discrepancy between the stored setting and current pot position
– 4HP
– +10/-0mA from Batumi II

Make Noise Strega Patches: Texture, Noise, Drone, Lead. Demo

video upload by Anton Anru

"«Noise & Texture» is a collection of 50 patches for a semi-modular synthesizer, Make Noise Strega.
Although Strega is often seen as part of the Make Noise trio (0-Coast + 0-Ctrl + Strega), it remains an intriguing standalone synth. My goal was to explore its full potential independently, without connecting other Make Noise devices. Strega is a truly unique instrument, offering inspiration for crafting the unusual and experimental timbres.

💾 Get the soundset: https://antonanru.sellfy.store/p/stre...

This collection includes lo-fi textures, drones, leads, noises, FXs, and rhythmical patches. They can take center part in a track or serve as a supporting element, creating an atmospheric background.

These presets are suitable for various genres of electronic music where experimental sound design plays a crucial role, including: Ambient, Techno, Minimal, Deep, Electronica, Drone, Industrial, Dubstep, Hardcore, Garage, Cinematic, and others.

Each page contains notes that explain how the patch works, what parameters are worth tweaking during playback, and how to develop the timbre during a performance. If you make all the settings consciously and try the things mentioned in the notes, you will learn a lot about the synth and discover its true depth.
To recreate these patches, you need up to 5 patch cords.

There are audio examples of all patches inside the folder with the soundset.

In most cases, I utilize the 1V/OCT input (indicated by a black cable in the images) to send note information to Strega. There are several popular methods to achieve this:
- Using a MIDI keyboard or controller with CV output, such as the Arturia Keystep or Beatstep.
- Employing the Make Noise 0-CTRL.
- Utilizing software like Ableton (or another DAW with similar capabilities) to send CV signals via an audio interface.

You have the flexibility to choose any of these methods and play notes manually with a keyboard or use their internal arpeggiators and sequencers. In some of my audio examples, I used the internal arpeggiator of the Keystep.

If you don't have any of these devices or prefer not to use them, you can still effectively utilize the patches. In this scenario, you'll be working with a single note or pitch, which you can set using the TONIC parameter.

Don’t forget to use Touch Plates for immediate modulations and expression.
