"It's funny...I started with a totally different idea that morphed into this!

At the key change I pressed a key on the lower keyboard to move the pitches up and also used a Q128 switch with a footswitch attached that allowed me to switch from sawtooth waves to square waves on the lead sound.

Drone - two oscillators tuned a fifth apart
Wind - noise run through a filter with LFO sweeping
ARP - two oscillators with different seq notes
Lead - tow oscillators slightly detuned and driven with LFO
Drums - noise through a bandpass filter being controlled with seq. Check out the video below on how that's done."

Analog Drums on a Modular Synthesizer

Published on Sep 16, 2019 George Benton

"Using a sequencer and bandpass filter to create drum sounds.
The Modular is a custom built system. Although the video says just a sequencer and a filter, (meaning no oscillators) it does require a noise source, VCA and ADSR.

The two voltages from the sequencer drive the frequency cutoff and resonance. The clock out from the sequencer goes to the ADSR gate in.

The frequency of the filter determines the 'pitch range' Higher range for cymbals, brushes etc. Lower range for toms, bass etc.

The resonance affects the "drum head" effect. More resonance for pronounced pitch like wood block or toms etc. Lower resonance for a more pitched noise effect."
