Patch Examples

East Coast Synth Voice:

Summary: 

The sequencer or keyboard sends voltages to 

saïch 

while 

simultaneously triggering the envelope generator. The CV output of the 
envelope generator opens the filter and VCA, allowing

 saïch

’s voices 

to pass through. More traditional East Coast patches would incorporate 
separate envelope generators for the filter and VCA. 

Audio Path:

• 

Connect the 

Out

 of 

saïch 

to the audio input of a filter.

• 

Connect the audio output of the filter to the audio input of a VCA.

• 

Monitor the audio output of the VCA.

• 

Set the mix profile to 

Cascade Crossfade

 and set the 

Fader

 to its 

fully left position, ensuring that all voices are equally present at  
the 

Out

.

• 

Set the fundamental frequency of 

saïch

 to a desired position using 

the 

Coarse

 and 

Fine

 knobs.

• 

Set the 

Detune

 controls of voices 2, 3, and 4 to slightly chorus 

against voice 1.
