"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 www.musicfromouterspace.com

GorF Kits, 2nd Run

via Vacoloco Ramblings where you can order them.

"Ladies and Gents,

I have some more GorF kits for sale. I’m also dropping kits 3 and 4, as I only sold 2. Most people seem to want either Kit 5 (90% of orders) or Kit 2 (about 9%).

I’ve added the Crystal Oscillator module to Kit 5, as a lot of people seemed to be struggling to find them, I have had to increase the cost to cover the cost of the part."

If you don't know what GorF is, click on the Vaco Loco label below for videos and more.

Simple modular sequence.

"Trying to do a clip with decent audio.

CGS59 controlling pitch of the function generator and also the division of the VC divider - acting as a sub oscillator. The sweeping sound is from the CGS39 with one input being the FG and the other a LFO."
