The Vactrol Pattern Synthesizer

This box is the outcome of an experiment with a CMOS binary counter/divider chip [CD4040]. The circuit is basically a single lfo as the clock for the divider and each 4040 output is summed to a single vactrol [led coupled w/ photo resistor]. This, in turn is controlling the pitch of a single square-wave oscillator. The result is beautiful 8-bit type video-game sounds.

    That there is the shit. I said it once and I’ll say it again…

    I love technology when it’s cool like that.

    Hey could you send me a schematic for that? Sounds awesome!

    Great grooviness! I dig both versions. Sweet tones. Anyway I could get the schematic? I want to put this into a guitar.
