Yuyo cmos synth - First try Attiny85 dco with analog cmos shaping and twin t filter

video upload by JIANT

"everything is from the synth to the zoom recorder, twin t drums, xor snare, pt2399, and cmos stuff.

attiny85 reseting the phase of 40106 oscilators, the digital control accepts 1voct from keysetp and go to the 40106 inputs through resistors, a little rc for filtering the pwm, and for this reason when you change the oscillator frequency you can get intervals and crazy stuff. is not orthodox but suits my need for Rich timbres. the dco goes to 40106 buffers , and then 4040 dividers, twin t filters, one for each of the two voices, one goes to env, vca, filter, delay, and the other one to clock divider and filter, to get the sub osc.

firmware super simple only for checking the conversion from filtered frecuency of the attiny85 to my 40106 non exponencial vcos.
currently is tracking 10 octaves really good, the trick is put a voltage divider in the cv in of the attiny because keystep has 0 to 10v and the attiny accepts 0 to 5v tehn the tracking inside the attiny converts o.5v oct to 1 volt oct. i dont know anything about coding but i made it with chat gpt and my design . source code will be in the coments ."

Gene Synths GX

New synth day. I’ve been waiting patiently for this to arrive and it was worth every second.

Such a beautiful lo-fi melancholic sound with a load of modulation. I fell in love with the sound when I came across the Gene synths website last year.

Great solid build quality and probably the best knobs of any synth I own ❤️

The interface is unique and encourages exploration and experimentation.

Can’t wait to send it through a looper.

Patch Notes

I’ve had Intellijel’s Metropolis for a long time and have used it on many songs. A family member bought me Metropolix as a gift and it was time for me to wrap my head around all the upgrades and new features, so that was the impetus for this track and the foundation it was built on.

Intellijel Metropolix to Livewire AFG. Modulating pulse width and harmonic animation with Ornament & Crime. That’s run through one of my fav filters of all time, the Cwejman MMF-2 modulated by the Tip Top Z4000 EG for a bit of snap but mostly as seen in the vid, manual modulation of the cutoff. Hands are handy.

Drums are sequenced by the Erica Synths Drum Sequencer with kick, hats and percussion all in random mode. The Drum Sequencer is controlling the VPME QD & QEX which I loaded up with my own selection of drum samples.

I used Make Noise Pressure Points/Brains for the main played lead, controlling pitch of the XAOC Devices Odessa. Gates fired from PP/Brains trigger another Z4000 EG which mults through a Synthrotek mult to a Pittsburgh Modular VCA and the Roland 521 VCF (The thing I keep looking up at, hoping it would wave or say hi. It never did, but it did an amazing job at filtering the Odessa.)

The little arp I added at the last minute. It lives on another rack which contains all my 5U stuff. Sadly it’s not in the video bc I didn’t know I was going to utilize it when I set up the cameras. Next time. The arp uses all Synthesizers.Com modules, sequenced by the Q119 and filtered by the Q150 Transistor Ladder filter.

Delays and reverbs from multiple Tip Top Z-DSPs. Some EQ & compression and maybe a delay in Cubase which mainly acted as my tape machine to record the performance. As I normally do when I patch, it’s all synced to Cubase clock using Expert Sleepers modules & Silent Way software.

If you read even one sentence from these patch notes, you get a lollipop and if you made it to the end you’re a true legend and clearly as nerdy as I am. 🙌"

The "Easel" Spirit in 3U - A West Coast Eurorack Deep Dive

video upload by Sean Graves

The following is in via Sean Graves, who had the following to say:

"The piece, 'The 'Easel' Spirit in 3U: Rebuilding a Buchla Soul in Eurorack,' documents my five-year journey to replicate the specific workflow and 'soul' of the Buchla Music Easel using a curated Eurorack system."

"This post explores the creative power of 5-step sequencing (the 'migrating downbeat'), the 'origami' of wavefolding via the Verbos Complex Oscillator, and the organic harmonic dampening of vactrol-based Low Pass Gates. It’s a technical yet accessible look at why the West Coast workflow remains the 'holy grail' for performance - based synthesis."

The full write-up follows, with a demonstration of the system in the video above.

The “Easel” Spirit in 3U: Rebuilding a Buchla Soul in Eurorack

The Buchla Music Easel is legendary. It isn’t just a synthesizer. It’s a self-contained performance ecosystem. For many of us, the “Easel” workflow is the holy grail of synthesis. However, instead of chasing original hardware, I’ve spent the past five years rebuilding its specific soul within the Eurorack format. Because everyone deserves a hobby, right?

The Chef vs. The Sculptor
Most East Coast synthesizers work like a sculptor. You start with a massive block of harmonic noise (Sawtooth or Square waves) and carve it away with a filter. The Buchla workflow is different. It’s like being a chef in your own Hell’s Kitchen. You start with basic, “bland” ingredients (sine waves) and spice them up with Frequency Modulation (FM), Amplitude Modulation (AM), your choice, and then fold until the sound sizzles.

My current rig recreates this spirit by focusing on three pillars: Uncertainty, Complex Oscillation, and the iconic Sequential Voltage Source.

Part One: The Modulators (The Brain)
In a true Easel style setup, the Tokyo Tape Music Center 5-Step Sequencer acts as the brain. While most modern sequencers favor 4-8-16-32 steps, the 5-step limitation is actually a creative superpower.

Industrial experiment with Hexdrums, Xenodrive & the Echolocator

video upload by Richard DeHove

"This is an experiment. It started with the thought: "What if I took just two voices from Hexdrums and feed them as individual outs left and right into the Xenodrive?". That felt a little raw even for me so I then added the Echolocator after the Xeno. After hooking it up I had a joyous 30-minute "jazz odyssey" of which this is the still-very-long-for-pure-drums cutdown version.

All three machines are tweaked as a single control surface and I don't think any machine here is the star. They all do their bit. Since there's no unaffected sound keeping things stable the Xeno work is quite restrained compared with the complete destruction of which it's capable, and likewise the Echolocator stays reasonably tame.

Was there a lesson from all this? Perhaps it's just that trying odd combinations is fun. On a more practical level I can certainly see that various sections could be usefully sampled as loops. To that end I've put together a pack of 16bit 44KHz loops at 110bpm that are on my Patreon page. Many of them can be usefully split left and right for further processing.

As usual there is no DAW processing and the volume has all the ups and downs of the original.

Small Town Boy/Bronski Beat (Circuit Tracks version)

video upload by Guinan

"Feeling a bit of 80’s nostalgia ('Stranger Things' anyone?) I thought the time had finally come to try and give this classic electro-pop anthem the Circuit Tracks treatment. Released in 1984 (40+ years!) it’s too easy to forget how ground-breaking the song (and it’s subject) was in the political climate of the Eighties.

The song itself is a simple but almost perfect pop song. It was programmed on an MC-202 Microcomposer and is reputed to have started life as an electronic disco version of the Sex Pistol’s 'Pretty Vacant'!

Yamaha DX7 is used heavily on the track (notably the presets ‘Harp1’ and ‘Bass1’), and additional Sequential Pro-One, Memorymoog and Linn drums. I managed to simplify the arrangement to program everything and the vocals into a single Novation Circuit Tracks. Everything you hear is being played and recorded live from the Tracks.

I'm pleased at how close to the spirit of the original I managed to get this time. I hope you enjoy the track and it brings back some memories for you too."

"More details for synth nerds
BPM 135
I don’t own a DX7 (sadly!) but the closest thing I have is emulation. The repeated ‘Harp1’ DX7 line (and the ‘Marimba’ break) was sequenced on the Tracks MIDI 1 and sampled as 4-bar loops from the internal MicroDEXED emulator in an M-Vave SMK-37 Pro keyboard. Each sample was then triggered (like a drum sound) at the required point in the song using the Drum 3 track.

Digitakt 2 is a Co-Producer – Track Breakdown

video upload by Sineway

"Obsidian is a track that emerged through working with the Digitakt II.

In this video, I break down the elements of the track, but more importantly how the ideas took shape. Not just what is happening, but how the Digitakt II actively shaped the music.

All synth sounds are sampled from the Arturia AstroLab 37. Rather than sequencing notes directly, full phrases and musical ideas were recorded into Digitakt II and then explored, reshaped and refined from there.

Drum sounds come from Digitone II, sampled and processed inside Digitakt II as part of the same workflow.

This isn’t just a track breakdown. It’s also the starting point for a short series of videos about how Digitakt II has changed the way I approach sample based music production, composition, and discovery. More on that very soon.

Eventide H90 + 0-Coast // The New Granular Engine!

video upload by Dexba

"Almost only the pedal is audible, bleah
That's the point!
Eventide recently came out with a surprise update, adding a completely new (and FREE, wow!) granular engine to the H90. For this video, I loaded two instances in parallel, one running the Cosmic Web algorithm (and as soon as you hear the video, you'll immediately understand why it's called that), and the other running Glitch, for those sparkly textures you hear here and there.
«but Dexba, you didn't even patch the Make Noise 0-Coast», yeah, exactly, because in this video the instrument is the Eventide H90, and I wanted the simplest (but best sounding) source I could use.
Plus, you get to experience a slow 0-Coast for once, since most of the other videos are focused on its plucking capabilities ;)
I hope you'll like it! 🧡"

ELKA EK 22 Vintage Synthesizer

Note: links to listings are affiliate links for which the site may be compensated.

via this Reverb listing

You can find demos in previous posts here.

"The EK-22 is an analog polyphonic programmable synthesizer from Elka. Its cousin, the EK-44 is a digital and expanded version of the EK-22. Although the EK-22 is analog, the oscillators are digitally controlled (DCOs) for better stability and programmability. The keyboard can be split and there are 16 performance patches to store any split, tuning and patch settings. There are 64 preset and 32 user sound patches of purely Italian style analog synth sounds.

Oscillators are very programmable with syncing, individual tuning, level and modulations. There are two six-stage envelope generators for total control of dynamics. The EK-22 is a capable synth similar to the Prophet 600 in programmability but more like the Matrix 6 in its look and push button style programming interface. The EM-22 is a keyboard-less desktop module version of the EK-22.

It has a very similar sound to the Oberheim Matrix 6 (and Matrix 1000) and the Prophet 600 Sequential, as it features the famous Cem3386 filter.

The synthesizer is in excellent condition; everything works properly buttons, sliders,Chorus (Juno 60 style) volume, audio output, and headphones, including the pedal inputs on the rear panel.

Aftertouch is also active, although it's a bit harsh; you have to press the keys quite hard to hear its effect, most likely because it hasn't been used in the last 30 years!
A small strip of foam has been inserted inside the front control panel to dampen the plastic noise, but this does not affect its functional or aesthetic behavior."

Waldorf M 1.11 Update Adds Varysaw VA Oscillator, CS80 Based Oscillator, Extensive FM & More

You can find the update here

Details form the release doc follows:

Disclaimer: This is an unofficial add-on to the M user manual, describing some of extra features added from firmware 1.05 up to firmware 1.11. This add-on also covers some complex aspects of the Multi Mode, which remains somewhat unusual.

Author: Vladi Salnikov aka VladiS.

Algorithms of FW version 1.11:

Varysaw: A VA oscillator ranging from SAW through PULSE to TRI.

Wave (red encoder): Mixes from 0 to 31 from SAW to PULSE; 32 is pure PULSE, and 33 to 63 mixesfrom PULSE to TRI.

Meta parameter: Pulse width for PULSE, adjustable from 5% to 95%.

CSAW: A famous Yamaha CS-80 saw oscillator with mutation towards a parabolic oscillator.

Wave : Controls the amplitude of the “step” component of the saw wave.

Meta parameter: Mixes between this saw wave and the parabolic saw wave.

Waveshpr: A SAW to TRI oscillator fed into a mild waveshaper.

Wave : 0 is pure SAW, 1-62 mixes between SAW and TRI, and 63 is pure TRI.

Meta parameter: Depth of the waveshaper.

TriplSaw: A stack of three SAW oscillators; two are detuned slightly higher and lower than the third.

Wave : Controls the amplitude of the “central” SAW oscillator relative to the two “side” SAWs.

Meta parameter: Detuning factor, from 0 to maximum detune.

S/T Fold: A SIN wave folding oscillator that folds the chosen crossmixed wave between SIN and TRI waves.

Wave : 0 is pure SIN, 1-62 mixes between SIN and TRI, and 63 is pure TRI.

Meta parameter: Folding depth.

FM 2 OP: Classic simple two-operator FM synthesis. OP1 (modulator) generates a sine wave that modulates the phase of OP2 (carrier). Both operators generate sinewaves; the algorithm's output is the carrier signal.

Wave: Maps values from 0 to 63 to harmonics ratios of 1 to 8 in stepped increments.

Meta parameter: Amount of phase modulation applied to the carrier.

"So I don't know much about this thing. I haven't even tried to power it up. Would probably be fun in noise sets or for learning electronics.

I have no reason to think it doesn't work but I have not had time to order an adapter to power it on. I was thinking to retrofit a more normal IEC plug on the back. Since it's 100v it will need a step down transformer (probably about $80 on amazon).

As far as shipping, the quote you're seeing is for me taking the panels off the rails and packing them more easily into a smaller box, but then mailing the rails to you. It might be possible for a similar price to keep it all together. I'm friendly, we'll work something out if this is destined to be yours."
