MM74C150N socket is included in the CIRCUIT BOM

The J201 JFET transistor in a TO-92-3 through-hole package is becoming harder to find

you should have a perfect Triangle waveform if everything was built correctly

The BLANK resistor on the PCB is used to center the waveform coming into the S&H section

CANVAS (BLACK) Buchla Now adjust the stepped trimcanvas kanvs The Canvas System is inspired by the early days of the "west coast" synthesis philosophy. Taking inspiration from the building blocks of the Buchla Music Easel and putting our spin on what that same system would look like in the paperface era. This is a full featured stand alone synthesizer that can hold its own against any instrument in its class. Modules included in this system 1973 Oscillator x 2 Triple Waveshaper 1973 VCF Noise Source
