"The Switcheroo features:
2 Voltage controlled oscillators (VCO), scaled to 1v/Octave
1 Voltage-controlled filter (self-oscillating and 1v/Octave too)
1 Attack-Release envelope generator
1 Low-frequency oscillator (LFO)
1 Voltage-controlled amplifier (VCA)
1 Envelope follower (that can trigger the envelope)
1 MIXER
1 White Noise generator
Some details about the features:
-->The original filter on the circuit was tweaked so that it self oscillates to get you the sine wave--you can hear it on tracks 2 and 4 on the website's playlist.
-->You can play the oscillators and the filter with your favorite CV keyboard.
--->The up/down switch on the Envelope Follower inverts the shape of the output. You can plug in a guitar, keyboard, drum machine, etc. into the envelope follower and it can modulate the VCA, oscillators, and filter! It also triggers the envelope generator, the Gate knob acts as the sensitivity of the follower to trigger the envelope generator.
--> The AR envelope can loop internally, so it acts like an LFO. It is very enjoyable and is used ALOT. When the EF (Envelope Follower) switch is on the down position, it is switched to this internal loop mode. When it is switched up, it triggers from the EF.
The synth circuit design is based on Ray Wilson's design. For more PCBs and analog synths, go to
