Patch Examples

East Coast Synth Voice:

Summary:

 The sequencer or keyboard sends voltages to 

Tš-L 

while 

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

Tš-L

’s signal to 

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

Audio Path:

• 

Connect the 

Square

Pulse

, and 

Triangle

 waveforms of 

Tš-L 

to three 

inputs of a mixer.

• 

Set the 

Sub Toggle

 to its left position, dropping the square waveform 

by one octave. 

• 

Connect the output of the mixer to the audio input of a fi lter.

• 

Connect the audio output of the fi lter to the audio input of a VCA.

• 

Monitor the output of the VCA.
