in the end, decided to do the obvious and just control the 4051 with a 4024 binary counter from the recycled parts bin, so it loops 1 through 8 sequentially. I actually tried using three separate clocks for the 4051 binary controls, but results were less random than i had hoped. I know it's as much of as a system as the other, but it seemed slightly less transparent and mechanical. Had them hooked up like a pendulum at first:ĥ - 4 - 3 - 2 - 1 - 2 - 3 - 4 (repeat) but that was too obvious, the goal being a 'human' feel to the switching.Ī small channel swap yielded better results: With only 5 presets and 8 possible connections, i repeated the middle 3 presets. I particularly like how it looks like we're floating in mid air. On the left is Champ's artistic director Serge Verstockt, layering on some pitch shifter and delay, on the right is The Wiz Roel Das, gating the oscillators and thus controlling the beats with Max/MSP + an Arduino, and i'm in the middle turning knobs controlling frequencies. We had a single 4093 on a breadboard, aka 4 oscillators, aka 2 pairs.Įach pair has a 'main' and a 'modulator' osc, and together they're gated by a control voltage sent from an Arduino. This is a small presentation of the workshop idea, trying to convince teachers and the like to invite us to their schools, basically. plan is to have them build their own simple synth (coupla gated NAND oscillators) and then try to have them perform a 'piece'.Īlways nicer to make noise than to have to listen to someone else talking about the history of it.
I was invited by Champ d'Action to collaborate on a workshop on analog synthesis, to be given to high school students.
