Vintage Moog Model 15 - almost final systematic test w drone jam at end

video upload by tonetweakers

"Here’s the real vintage Moog model 15 we meticulously refurbished a few years back and sold to our client just recently.  we hoped this would be its final test, but while filming, I noticed a couple really minor things that’ll be fast and easy to sort out. (One cutoff freq pot crackled slightly, we need to make sure we can’t improve the octave switch tuning (which is the same across all 3 oscillators) and we need to check oscillator tuning with an external 1 volt per octave control voltage source). The jacks themselves are all fine, but a couple of the cables it was tested with are dirty and caused a bit of crackle. (These cables aren’t part of this sale).

We meticulously service and systematically test our high end gear multiple times before it leaves here so it meets and often exceeds our customers expectations.

Facehugger r013 Chain2 demo

video upload by flightofharmony

Update: "Re-upload because the text wasn't visible."

"The chaining feature of the Facehugger function generator is working!
This is a two-unit demo, showing some of the features and use of the Tail output for emphasis

OBS output the file in 640x480 for some reason, my apologies. Not gonna redo a pre-beta demo video though.

Caption text:
00:15 In this video, the Head Out is connected to the Infernal Noise Machine VCO CV input. Next, the Tail Out is connected to the INM IMP Frequency CV input, adding emphasis to the notes played by the Tail stages.

00:33 The Facehuggers are chained (in series) via the rear chaining headers. The Head unit outputs all stages, while the Body and Tail units only output their respective stages.

00:43 The controls of each unit only affect the output of that unit - Length, Level, Speed, Curve, Root, Scale, Direction, Glide, etc. Trigger and Gate signals are rerouted to the Head unit and start/restart/maintain the full sequence.

1:36 Connecting the Tail Out to the INM VCA2 CV input

1:49 Now changing various control settings - Direction, Root, Scale, Curve.

3:08 That's it for now, thanks for watching!
Next will be a demo of a 3-unit chain, after I get the third unit working."

Malstrom ARKAN / dual ringmod VCA with variable curve / smart voltage utility hub

video upload by BRiES

"This video is all about the features of ARKAN, a dual voltage polarizer by Malstrom. ARKAN is a two channel four quadrant multiplier (bipolar vca or ring modulator) with built-in amplification, clipping, ofsetting, inversion, ... and a variable curve response (linear - exponential). It can be used to clip, scale, attenuate, reshape, mix or straight up mangle the stuff you send through one of it's several inputs."

Korg Z1 / Tr-608

video upload by Faustola

"Korg Z1 is a really underrated synth. You can do some really nice evolving sounds using both VA and PM engines. Also even though the filter is digital, I find it quite capable. In some forums people say it cannot be synced via midi, but this is untrue at least in the later versions."

AI Synthesis Introduces the AI012 Eurorack Wave Animator Eurorack Module

video upload by AI Synthesis

"A Demo Video for the AI012 Eurorack Wave Animator

The AI012 Eurorack Wave Animator produces two pulses per input wave cycle with voltage controlled pulse width, distance, and amplitude of the second pulse.

It can be purchased as a module, or DIY Kit and PCB/Panel Set at"

AI012 Wave Animator BUILD VIDEO

"The AI012 Eurorack Wave Animator produces two pulses per input wave cycle with voltage controlled pulse width, distance, and amplitude of the second pulse.

The manual is here.

The DIY Eurorack Wave Animator build guide is here."

Update: press release follows:

Portland, OR, USA August 17, 2023 – AI Synthesis has released the AI012 Eurorack Wave Animator in both a built and guaranteed version, as well as in kit and PCB/Panel format.
The AI012 Wave Animator is a Waveshaper/VCO Expander that produces two pulses per input wave cycle with voltage controlled pulse width, distance, and amplitude of the second pulse. This design was adapted (with permission and a few changes) from Ian Fritz’s Double Pulse Generator circuit. Some changes were made to the circuit in development.
While the circuit is all analog, the AI012 Eurorack Wave Animator’s pulse wave outputs have a range of timbres from analog wave folding to digital sounding chimes.
The Width of each Pulse is controlled by the AI012 Eurorack Wave Animator’s Width knob and corresponding attenuatable cv input.
The Distance between the second pulse and the first pulse is controlled by the AI012 Eurorack Wave Animator’s Distance knob and corresponding attenuatable cv input. The resulting waveform can have two distinct pulses, or staircase style wave-shapes.
The Amplitude of the second pulse is controlled by the AI012 Eurorack Wave Animator’s Amplitude knob and corresponding attenuatable cv input. It can be negative or positive in voltage value.
In addition to creating new audio rate waveforms, when used as a sequencer, the module can create interesting rythmic variations when the pulses are used as triggers and cv is used to stagger the second trigger.
It comes in both Silver Aluminum versions and Black PCB FR4 versions.

“In the year 2000, I was in college and obsessed with modular synths, but could barely afford to eat. I knew it was possible to build your own synth, but there wasn’t anyone, or anywhere to turn to for advice. In the past decade, much more information has been published online, and in 2013 I started down my path to DIY modular. Even with all of the information online, there still lacked a single, simple, comprehensive guide for those looking to build their own synthesizer. I want AI Synthesis to be that guide. Prior to building my own synth, I was a dreamer, after building my modular, I felt I had awoken. I want to help others do the same.”

User Petition to Make Waldorf Kyra Open Source

This one is in via Sérgio.

You can find the petition here.

Details via Fabio Montarsolo:

"Waldorf acquired the valkyrie project from Mr. Manuel Caballero back in 2018. After a quick cosmetic change, they put it into the market with the name Kyra.

Despite strong requests from the community of users, they did not release any significant firmware update. Now in 2023 they declared no further firmware update is to be expected.
The valkyrie/kyra is an FPGA implementation, so in practice it is a software designed synth, with much lower limits of hardware ones.

We as kyra users asks Waldorf to release the code of kyra firmware into open source in order for the community to take over their unfinished work."

Note the Kyra was initially the Exodus Digital Valyrie as pictured. It was picked up and rebadged as the Kyra by Waldorf.

Dance jam with Roland T-8, S-1, Crum Drum

video upload by Jay Hosking

You can find more info on the Crum Drum here.

"Please support my work on Patreon:
A live, semi-improvised jam performed entirely on hardware.

Text, phantasmagoric visuals, masking, art, and more created by Vincent Venoir. Please check out his music project here!:

I've been travelling quite a bit over the last few weeks and decided to get the "Rolcas" to keep me company while travelling. I have been super impressed with the T-8, J-6, and S-1, and been having a blast while sitting in hotel rooms or ferry line-ups. The T-8 in particular leads to instant fun, and the S-1 is a surprisingly deep synthesizer with fantastic sound.

Here, I made a pattern from scratch on the T-8, quickly transposed something I had noodled on the S-1, and then performed it on the spot. I also added in the Crum Drum, another cheap drum machine, for some fun percussive performance. It made a great combo with the Rolcas (although its synch occasionally lost a 16th note). The three together made a fantastic, fun, and fast jam.

It was the fun of these devices, and this jam, that made me think to reach out to Vincent and see if he wanted to make some of his magic on the video. He really captured the spirit of the jam, and I was delighted by the end results!

Roland T-8 - Drums and bass
Roland S-1 (+ XLN RC-20 plug-in for a bit of dirt/warble) - Chords
Nyström Crum Drum - Percussion

Written a few minutes before recording. Performed and recorded live, with EQ, compression, and limiting on the master.

Thanks for listening."

Vermona twinVCFilter – Part 2: more filter sweeps

video upload by vermonagear

00:00 | Intro
00:36 | filter sweep lowpass, 24 dB/octave with overdrive (no resonance)
01:03 | filter sweep lowpass, 24 dB/octave
02:06 | filter sweep bandpass, 12 dB/octave
03:03 | filter sweep highpass, 12 dB/octave

"In the second video about twinVCFilter, we explore its serial mode. Connecting both filter sections in a row doubles the slope, which results in 24 dB/octave low- and highpass filter and a bandpass with 12 dB/octave.

Like in the first video, we sweep through all filter types with different resonance settings."
