Eurorack "West Coast" Synth Voice Patch Breakdown / Tutorial

video upload by Transduction Signal

"This simple patch is a synth voice that is inspired by "West Coast" synthesizers like Buchla and Serge modulars from the 1960s and 70s. This patch also has a signal flow similar to the Make Noise 0-Coast. The basic idea behind the patch is to take a simple waveform and fold it to add harmonics, then a lowpass gate is used to control the dynamics of the sound.

Modules we used:
- AJH MiniMod Vintage Transistor Core VCO
- Random Source Serge Wave Multipliers
- Erica Synths Black Dual ASR EG
- Erica Synths Black LPG
- Korg SQ-1 Sequencer

The Patch:

- Audio
- VCO triangle or sine wave into the wave-folder audio input
- wave-folder audio out to the lowpass gate audio input
- the lowpass gate's audio out is the final output sound

- Control
- 1v/oct from sequencer or keyboard to osc 1v/oct input
- sequencer gate out to gate in on envelope generator
- envelope generator out to wave-folder CV input
- sequencer gate out to LPG "ping" input

Extra things to try out:
- the gate length of your sequencer will affect how plucky the sound is, so try adjusting it
- different wave-folders will have different sounds so try out a few if you have them
- if your wave-folder doesn't have a CV fold amount control you can use a VCA before the wave-folder and control that with the envelope
- if you don't have a lowpass gate you can try this patch out with just a filter or VCA after the wave-folder with an envelope opening it
- try other waveforms besides triangle and sine into the wave-folder
- try running more than one oscillator into the wave-folder and see how the multiple oscillators interact
