"Study Music"

I took the GREs this week, which means I haven't done much in the past couple of months beyond going to work, coming home and studying. Fun, fun, fun.

In any case, I've found that studying to monotonous, repetitive music works for me, and figured this out by having essentially the same patch up on the modular for three weeks, bleeping and blooping away. Every day I'd turn a knob or add a cable, slowly building it up from a single droning oscillator to this-- where it was on test day:

Thanks, 11hz! I really enjoyed putting it together and letting the sequence(s) play out for hours at a time.

Thanks Jordan!

Maths is providing a complex frequency modulation source for the Z3000 VCO:

Maths is set as a pair of audio-rate LFOs, with the output of Channel 1 sent to the "both" timebase input of Channel 4.

Then, the output of Channel 4 is sent to the FM input on the Z3000 VCO. Both the Z3000 and Channel 1 (the modulator in what is subsequently an intra-Maths FM patch) are being controlled by the same 160/138c "Binary Zone" sequence (where divisions of the master clock are being scaled as pitch values).

In short, Maths is acting as two oscillators. The audio-rate frequency of one is modifying the audio-rate frequency of the other. The output of this is modulating the pitch of the Z3000.

The result is the complex, almost noise like tone from what should be the sine wave output of the Z3000.

I'll put together a Maths-only video soon! I've only scratched the surface with this one!!
