Living the Euclidean Dream - A Hands-Off Eurorack Patch

video upload by Scrapcode Modular

"A slow, relaxing musical meditation on Eurorack. No post processing - audio goes straight from the rack's headphone output to the camera input.

Patch notes:

Audio signal flow:

4x Osciallators from @scrapcodemodular QUORD - Chord Sequence Oscillator (prototype)
into
4x inputs of Doepfer A-105-4 Quad Poly VCF (low pass filter)
into
4x inputs of @behringer Four Play VCA
into
4x inputs of @Dreadbox-synths Psychosis (adding panning movement and delay effect)
into
Stereo input on @behringer rack mixer (adding stereo chorus/reverb effect)
into
Stereo input on camera

Envelope modulation:
@scrapcodemodular WONK - Quad Envelope Generator is controlling both the VCF and VCA for each of the four notes individually. This is being triggered by the @scrapcodemodular AXIOM - Euclidean Rhythm Generator, which is set to a 15 step pattern. The trigger for the bass note is multed to the QUORD's 'Play Next' input to progress the chord each time a bass note is played. This gives a slow 12/8 feel due to the 8 chord sequence, but as AXIOM is running over 15 steps, any repetitions in rhythm are spread throughout the pattern rather than being repeated each bar.

LFO modulation:
As well as the Psychosis adding stereo interest, slow LFOs have been patched into various parameters on AXIOM to keep the rhythm changing - not so much as to be jarring or unfamiliar, but enough that the same order of notes almost never repeats. Further cyclical modulation has also been applied to the WONK parameter (changing envelope timings) and the filter's cutoff frequency. LFOs have been attenuated using @scrapcodemodular QUATT - Multenuverter."
