This is a PulpLogic Lunchbox build of an Etherwave Plus Theremin Voice.

Outs (headphone, stereo, are on the right)

The Theremin control inputs will require customization:

Three 1/4" Jacks on left, labeled Vol, Pitch & Gate

Vol CV 1-10V IN maps to 6 buffered outputs, taking 1 1/2 tiles

Pitch CV -2.5-4.5V IN maps to 6 buffered outputs, taking 1 1/2 tiles

Gate up +8V IN maps to 4 trigger outputs (using Gate-to-trigger circuit)

The Etherwave Plus Gate Up is converted to Trigger for these reasions:

It's only immediate use is to trigger Syncs on oscillators and LFOs

But, we want to retrigger Syncs on other events

An OR circuit would never fire further events if the Gate was connected and always UP

So, we convert Gate to trigger, so it is normally zero, allowing other triggers/gates to fire
