Multi-timbral Split by Adaerus

Multi Timbral Voice Split Polyphonic Sequencing

The idea for this patch was to separate the oscillators and the envelopes and route them to different voices in paraphonic mode.

Osc 1 = voice 1. Amplitude of voice 1 is controlled by Envelope 2

Osc 2 = voice 2. Amplitude of voice 2 is controlled by Envelope 1

Filter is controlled alternatively by the two envelopes:
Mod Depth controls the depth of Envelope 1 filter modulation - voice 1
Env Dept controls the depth of Envelope 2 filter modulation - voice 2

This can be used with two independent sequences to create duo-phonic (polyphonic) lines.

More in depth explanation:

1) Separate oscillators:
OSC 1 -> VCA IN
OSC 2 -> in ATT1

2)Create two VCAs
ENV 2 -> VCA CV
ENV 1 -> ATT1 CV

3) Mix (Sum) both voices
VCA -> SUM 1(B) - voice 1
ATT1 -> SUM 1 (A) - voice 2

(For true polyphony use the VCA and ATT1 outputs to route to two filter modules instead of summing them and trigger the envelopes independently by connecting E.GATE 1 and E.GATE 2. Next steps can be skipped.)

4) Create sequence to trigger envelopes independently (SQARE LFO is internally routed to MULT)
Trigger 1:
MULT1 -> INVERT IN
INVERT -> E.GATE1
Trigger 2:
MULT 2 - E.GATE2

5) Add filter

SUM 1-> VCF IN (see step 3)

6) Independent Filter Control (sequenced, non simultaneous)
ENV1 -> FREQ MOD
ENV2 already routed to filter through ENV DEPTH

The Overdrive and the VCF1 and VCF2 routings to SUM B inputs can be bypassed if VCF1->DELAY IN.
