ASHIKO is a quad ping-pong VCA designed to create multi-directional stereo sounds starting with mono sources.

Plug an input into “I” and a LFO in “V”. Connect the two outputs “O” into a mixer / output module.

The switch at the bottom is used to set the mono – stereo mode of the VCA. The other toggle is to select between a hard and a soft pan curve. Visual feedback of which of the two output is currently open is given with two blue LEDs.

It’s called see-saw VCA because when an output is linearly opening the other one is alternately closing following the behaviour of the CV source. Different kind of controls – pulses, envelopes, complex waves - will make the VCA react in a distinctive way.

With stereo mode active – bottom toggle switch on - connect a triangle wave from an LFO in the V input. Rise the frequency of the LFO to speed up the opening-closing action of the VCAs, resulting in a faster stereo and phasing effect. Make this panning harder or softer with the other toggle switch.

Experiment with all kind of input waves to get unique results.
