Behringer System 100 ~ harmonic drone

A triple oscillator drone patch with the System 100 and plenty of imperfect harmonics. The all analog nature of the System 100 without quantization is perfect to create outside the box melodies.

Patch notes:
1st VCO: Pitch is controlled by the sequencer (module 182, manually advanced), the pulse wave goes through a VCF (module 121). The VCF cutoff is modulated by an envelope (module 140). The envelope trigger results from a divided clock rate, using the gate delay (module 172).
2nd VCO: Pitch is modulated by two gates (module 173) that are switched by an LFO fed through a S&H (module 150). The two gates output a constant cv to the VCO when switched on, leading to a simple three note sequence. The VCO pulse wave output goes through a VCF (121), modulated by an envelope (140) that is triggered by the main clock.
3rd VCO: Pitch is controlled by the second sequencer row, VCF cutoff receives the same envelope as VCO 2.

The mix of all three voices goes through the phase shifter (172) and some reverb + delay.
