This ribbon synth have a Rene Schmitz voltage controlled oscillator (schmitzbits dot de) that run into a 24dB low pass filter, also have 4 modulation sources; 3x LFO and an envelope generator AD type. Is a very simple synth but it can make a good analog sound. All modules are MFOS (musicfromouterspace dot com) except the oscillator.
The ribbon is a flexible resistor (softpot), but do not have S&H so when you do not touch the membrane the sound return to the original pitch.
There are CV-gate input for external control.
