Korg MS-03 Signal Processor

via this auction
"Korg MS-03 vintage pitch to voltage converter interface. This unit produces VCO CV (control voltage) signals and trigger (gate) signals so that you can use an electric guitar, microphone, or other transducer output (from an acoustic instrument, for example) to "play" a synthesizer. A variety of remote control input jacks let you use foot switches for more freedom and flexibility during live performance. With this amazing unit you can instantly put together your own guitar synthesizer, vocal synthesizer, etc., by simple connection with any synthesizer equipped with VCO CV IN and TRIGGER (Gate) IN input jacks."

Oberheim TVS

"OBERHEIM SEM Two-Voice with built in step sequencer. Oberheim's first synthesizer was a single-voice mini-module called a SEM (Synthesizer Expander Module). However, in 1975, Oberheim created their first compact, programmable and polyphonic synthesizer by coupling two SEM modules to a 37-note keyboard and a simple analog sequencer. This was what became the Two Voice. Oberheim achieved a polyphonic sound not yet seen in ARP and Moog gear at the time by hard-wiring the two monophonic SEMs into the compact keyboard design. In 1976 Oberheim came out with another module, the Polyphonic Synthesizer Programmer (see SEM). This could memorize the control voltages of many parameters for up to eight SEM modules. When these were added to the Two Voice, Oberheim finally had one of the earliest programmable and polyphonic instruments! Released alongside the Two Voice also came the Four Voice which had four SEMs installed, and a larger 49-note keyboard. Two voices was great in 1975, and eight voices was pretty monstrous in the later seventies. But, a major drawback to these first Oberheim synths was that polyphony was achieved by having multiple modules. This meant that each voice had to be independently programmed. This also means that each voice has its own filter, making real-time filter sweeps of all your voices more than a handful! Fortunately the sequencer comes in handy for controlling each voice/module independently."

YUSYNTH EMS Diode Ladder Filter

via YuSynth where you can find more info:

"Well, here is another classical and very special filter : the EMS diode ladder filter!This filter has a sound of its own and is the signature of the classical Pink Floyd's song "On the run".

My aim here was to design a quite faithful copy of this mythic filter while using components that minimize the burden of selecting a great number of matched transistors. This is why I used transistor arrays (CA3046, CA3096). However, because the CA3096 has become a rare part and is now overpriced, I have also designed a PCB with discrete trannies to replace it. As for all the other filters of my YUSYNTH project, I have added an input and an output buffer to adapt this filter to the input and output levels of my modular system.

I also added an input for voltage control of the resonance : everything was there in the original module but was not made available, probably because of the limited size of the patch pin matrix of the AKS/VCS3...

Because, my power supply standard is +15/-15V, I have included a power regulator IC (78L12) to convert +15V to +12V and a single transitor voltage regulator -15V to -9V (I wanted to use a 79L09 but changed my mind when I realized that this voltage regulator is quite a rare part and is difficult to source)."

Waldorf Blofeld Presets

YouTube via thekilon. via fischek. Audio comes it at :50.
"The audio was recorded separately to Ableton Live and then imported back to the video for extra Quality.

WARNING!!!!!!
-----------

THE PRESETS OF THE BLOFELD ARE MONOTIMBRAL BUT THE SYNTH ITSELF USES UP TO 16 TIMBRES. THIS MEANS THAT THE SOUNDS YOU HEAR IN THIS VIDEO USE ONLY 1/16 OF THE TRUE POWER OF THE SYNTH!!!!"

Evolver vs. Freqbox

YouTube via Analogger
"This is a patch I came up with on the Evolver and synced it to my sequencer. Jomox M-Base for the bass drum, the snare and hi-hat are from a Roland SH-32. The Virus is used for a basic arpeggiation. Also included: Roland MKS-30 along with the Moogerfooger Freqbox oscillator thru the Moogerfooger Lowpass Filter. The Strat is thru a Damage Control Demonizer. The Korg Kaoss Pad is set to a synth patch.

For the Freqbox I patched the oscillator out into the Lowpass Filter. I tuned the oscillator to E and wrote a stepped pattern for the midi-to-cv converter which step-modulated the filter cutoff frequency. Control the voltage!

The idea for this started with the patch I created on the Evolver. It never ceases to inspire something musical and/or strange."
