CV extension mod. for SY-CORE

CV extension for SY-CORE.
The mod is very simple: all you have to do is to wire a few points from the SY-Plus PCB to the middle board of SY-CORE and it's done.

• VCF CV IN: control of the VCF freq
  In parallel to "Width" (amount of internal envelope to VCF)

• VCA CV IN: control of the VCA
  Cut the internal envelope modulation
  Use an ADSR envelope then SY-CORE becomes a standard 2 VCO mono synth with sustained notes possible.

• Decay CV IN: control the time of the internal envelope decay.

• ENV OUT: internal envelope output
