Buchla Timbre
This is basically a clone of the Buchla timbre found in the Easel. I have added a simple tri2sine converter input, along with the regular input, and buffered output.
This version uses thru-hole components.
A dual 8HP smd based version is also available - https://www.nonlinearcircuits.com/modules/timbre-and-timbre
