Paia 2720 + 4700 (1970's DIY modular synthesizers)

video upload by Tinfoil Cat

"I've been telling myself for too long that I should post more Paia videos. This is an old video shot before I fixed the keyboard on the 2720 (broken sample and hold as you might hear). The main part is 4700, the 2720 helps out with a fourth VCO. The spring reverb is a little noisy.

These were available as kits from Paia starting in the 1970's. The 2720 is closely related to the 2700 that arrived on the market over 50 years ago!"

Interesting side note via sdiy.info:

"Frac rack, FracRak or Frac, from Fractional Rack, is the modular synthesizer format designed by John Simonton of PAiA. It has a mainly USA following largely through the popularity of Blacet modules.

Like the Eurorack format, Frac is considered a 3U format..."

Analogue Solutions | Live Jam | Fusebox X and Fusebox | No Talking

video upload by VCO USA

"A live track featuring two Analogue Solutions Fuseboxes- The Fusebox X, and the original Fusebox.

One is doing the '303 / Acid' sounding lead, the other is doing the bouncing bassline. Clever use of the built in 'Patternator' let both sounds bounce between low, mid, and high timbres.

To me the Fusebox really does sound special. It has my personal favorite sounding filters of any synth ever made- An incredible Multimode 2 pole filter (Low pass, Band pass, High pass, and Notch). Notice the resonance is maxed, while still being smooth and bright, but without being sharp or ear piercing.

Both fuseboxes are sequenced with Ableton Live, with a touch of overdrive, compression, and reverb. Off camera- a poly synth is playing some simple chords, and just 3 drum sounds make the entire drum track.

Enjoy!

Dreadbox Telepathy Bundle Demo | No Talking

video upload by VCO USA

"Here we play a few excerpts from sounds we've made with the Dreadbox Telepathy Bundle.

The Dreadbox Telepathy bundle is a Eurorack format synth with very interesting MIDI controlled capabilities. You can control each module individually, link them together to create up to a 6 voice polyphonic synth, or mix and match to create wild multi-timbral patches.

The bundle consists of 6 x Dreadbox Telepathy Full Voice Synth modules and 1 Dreadbox Psychosis 6-Channel Stereo mixer with 4 FX. They are now available from your favorite synth shops.

All sounds in the video are made only with the Telepathy Bundle. No other external FX or synths were used. Enjoy!

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 https://aisynthesis.com/product/ai012..."

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.”

This Synth Is Possessed... PWM Malevolent

video upload by VCO USA

"True story... I left my studio for a few minutes and when I came back I realized I left the LFO on with a patch that I was trying to create. In that moment, I realized Malevolent is more evil and deep than it appears. This is what I walked into when I got back to my studio which inspired me to tweak and evolve what was already there. A happy little accident.

I added a little bit of reverb and delay for a dramatic effect. Sounds like the beginning of a score to a horror movie if you ask me. "

Korg Mono/Poly Analog Synthesizer SN 373493

via this auction

"A cool analog monophonic/polyphonic from Korg. It has 4 VCO's which can be shared in 4-voice Polyphonic mode, or linked in Unison for a versatile monophonic lead. Each VCO has its own level, tune, and waveform type control. Waveforms include triangle, sawtooth, variable pulse wave. It has a great VCF (filter) section as well as 2 envelope generators (one for the oscillators and one for the filter). There are also 2 individual LFO's which can be used to modulate the Pulse Width, envelope and Arpeggiator independently.

A very flexible and fun synth. Other cool tricks up its sleeve include chord memory and an effects mode in which oscillators have a variety of ways to be synced. The built-in arpeggiator and sequencer can run all 4 VCO's at a time or cycle through each voice per note! There's also portamento, CV/Gate, VCF and VCO mod inputs, white noise generator, and the pitch/mod wheels can be assigned to control LFO, pitch or the filter. Its sound quality is nice and very Korg. This synth is used by Hardfloor, Tangerine Dream, The Orb, 808 State, Juno Reactor, Megaton Matt Haines, Freddy Fresh, and the Chemical Brothers.

This unit has been used on countless records by bands like Deerhunter, The Kaiser Chiefs, The Magic Gang, The Big Moon, Childhood and many many others! Used and maintained in a smoke-free studio. I’m happy to ship to the Continental USA or offer local pickup. Any other location please reach out to discuss terms.

Keyboard Bed may need some servicing, same as the wheels on the left but apart from that, its in really great shape! Sounds fantastic!"
