3 Modules #22: Maths, Brain Seed, µScale

Published on Sep 7, 2017 Comparative Irrelevance

"We all suspected Maths is evil. Now there's proof.

Patch notes:
I'm using Maths as a dual oscillator drone voice by cycling both functions at audio frequency rate. The "both" inputs are handy for this, as they let you change the rise and fall rates simultaneously, without altering the waveform. Unfortunately they don't track 1V/Oct, so I'm using channel 3 to attenuate the incoming pitch sequence to try to approach some semblance of musical intervals here. As you can see I'm also continuously tuning the oscillators via "the blue knobs"™, looking for interesting beating or harmonic intervals between the oscillators. Changing the rise or fall rate individually has the neat side effect of changing both pitch and harmonics (waveform) at the same time.

To control the drone pitch, I'm using brain seed to generate a stepped sequence. It's receiving a steady external clock to get the patch going. This sequence is then being quantized by the µScale, just to narrow down the random selection a bit (because Maths doesn't track pitch anyways, remember).

Finally, I've cheated in some extra delay and reverb here, to get that proper evil drone ambience going.

Thanks for watching!"
