Buchla and MonoMachine as looper

YouTube Uploaded by 7thDanSound on Aug 17, 2011

"Using the MonoMachine as a looper with the Buchla. I took one channel and put a very long delay on it with almost unity gain feedback. As you can hear there's a lot of bit crushing going on as I guess they didn't put enough memory into it to do this. Maybe I'll have to get the Octatrack. There's about 40 minutes of audio recorded but for now you'll have to mail me to get it.

via this auction

"Vintage analogue 2 VCO Synthesizer Made In GDR with MIDI retrofit designed by CHD-Elektroservis

2-VCO monophonic analog synthesizer (each saw, 2 square waveforms, noise - all cen be used simultaneously).
24 dB/oct analog VCF filter with 4 knobs (Brilliance, CutOff, Resonance, Contour) - exact copy of Moog filter
LFO to modulate the VCO or VCF sections
ADSR VCA envelope.
Preset VCF and VCA settings as well as a Manual mode

The MIDI Interface
VS-MIDI retrofit enables Vermona Synthesizer to be controlled via MIDI. It controls VCO, VCF, VCA and EG circuits of the instrument. All original features of Vermona Synthesizer are not changed - the instrument can be still used the same way as before the interface installation.

Main Featrures:
VCO Key Shift (0 to +84 semitones)
VCO Pitch Bend Range (+-0 to +-12 semitones)
VCF Mode (EG / Gate / Controller)
VCF Key Follow (+-100%)
VCF Velocity Amount (0 - 100%)
VCF Channel Aftertouch Amount (0 - 100%)
VCA Mode (EG / Gate / Controller)
VCA Key Follow (+-100%)
VCA Velocity Amount (0 - 100%)
VCA Channel Aftertouch Amount (0 - 100%)
EG Retrigger Mode (Off / Fix / MIDI)
EG Retrigger Rate (0,4~20 Hz or MIDI clock)
"Note On/Off" (incl. Velocity sensitivity)"

Arduino SpeakJet Module Prototype

Arduino SpeakJet Module Prototype from ignacio dacio on Vimeo.

via Ignacio Dacio on The MATRIXSYNTH Lounge

"This is a module I built early this year.
It is an Arduino driving a SpeakJet chip to produce allophones and weird synth sounds.

It works on an algorithm coded in Arduino, which is basically a sequence with a variable, the slide potentiometer position amount, which makes the sound change.

The rythm and velocity must be changed into the code.
It has an LCD to display the amount of the slide potentiometer. It says "Voice Pitch" but it could be anything.
The first slide potentiometer is the volume.

Based on the sequence you can produce robot voices.
The easy way should be to add another chip which translates text into sound."

"Hand made Synth.
8 oscillators out of 4 556 ICs
Each osc modulates the next one."
