Day 6: Synth sequencer prototype and first steps making

The video above shows the modded Gakken synth being triggered by two microswitches on the turntable. It’s possible to get three notes from the switches: when either one is switched, or when both are on. Then the knobs on the synth control the pitch and other parameters.

This shows that trigger inputs work but also that the microswitches are pretty clumsy and not delicate enough really. I’m going back to electronic contacts, in pairs, touching metal placed on the record. I can do this by using the automated cutter to cut out sticky-backed copper sheet.

I began the process today – images below of some designs, and detail shots of the prototype. The beauty of this system is that it will also work on the the cymbal solenoid trigger (as currently set up) and various combinations of both.
