On the go, on a rope, and on four feet.

The Switcheroo features are:

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 too)
1 MIXER
1 White Noise generator

We hope that these mp3 are demonstrative of different effects, sounds, features of Switcheroo.

-->Track 6 demonstrates the envelope follower's gate triggering the AR, going to the filter...I think.
-->There were many things happening all at once at different points, but we're sure that when you have it in your hands,
your ears become a lollipop concept
and your hands will be switching patches like witches.

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 playlist.

-->There is a glide circuit (portamento). You can use it with the CV inputs on both oscillators.

-->The filter is also 1V/octave. So you can play the oscillators and the filter with your favorite CV keyboard.

The CV input goes to both oscillators, and when they are linked with the link switch turned on, Osc 1 becomes the main tune for both oscillators.

--->The up/down switch on the Envelope Follower reverses/inverts the shape of the output. You can plug in a guitar, keyboard, clavinet, 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.

You can play and listen through headphones, the headphone amp is LOUD!

--> Takes 12vAC.
