circuitbenders phonic taxidermist

Something I’ve been working on recently.

It’s the Circuitbenders Phonic Taxidermist modified with gate inputs to switch the different frequency bands of the chopper circuit in and out.
The modification uses another CD4066 and comparators built with an LM339. This enables any signal passing the one volt threshold to turn the switch on or off – so envelopes, lfo’s as well as gate signals. Haven’t had a chance to record it but sending fast lfo’s into these inputs does really nice things!
This is my first test of the circuit. Already thinking that voltage control over the chopper oscillator might be rather nice!
Here’s the schematic for my modifications: gate-mods-for-taxidermist.pdf
