VCO 2

 (R4, C1) 

Audio output of VCO 2

See VCO 1.
 

VCO 2 SUB 1

 

(R4, C2) 

Audio output of VCO 2 Sub-oscillator 1 

See VCO 1 SUB 1. 

VCO 2 SUB 2

 

(R4, C3) 

Audio output of VCO 2 Sub-oscillator 2 

See VCO 1 SUB 1. 

VCF EG

 

(R5, C4) 

Envelope output of the VCF envelope 
generator

This is normalled to the CUTOFF input, 
but try routing to any VCO for enveloping 
FM or a RHYTHM for complex sequencer 
motion. 

SEQ 1

 

(R7, C1) 

Sequencer 1 output 

This can be routed to VCO 1 with SEQ 1 
ASSIGN buttons, or use a patch cable 
to route it to any VCO 2 parameters, the 
CUTOFF for sequenced filter motion, 
the VCA for sequenced accents, or any 
RHYTHM for per-step rhythmic changes. 

SEQ 1 CLK

 (R7, C2) 

The clock output of SEQ 1—generates a 
clock whenever SEQ 1 moves. 

Useful for synchronizing with external 
instruments, play with patching it to the 
CUTOFF or any VCO for very fast punchy 
attack transients. 

SEQ 2

 (R7, C3) 

Sequencer 2 output

This can be routed to VCO 2 with SEQ 
2 ASSIGN buttons, or use a patch cable 
to route it to any VCO 1 parameters, the 
CUTOFF for sequenced filter motion, 
the VCA for sequenced accents, or any 
RHYTHM for per-step rhythmic changes. 

SEQ 2 CLK

 

(R7, C4) 

The clock output of SEQ 2 

This generates a clock whenever SEQ 2 
moves. See SEQ 1 CLK. 

CLOCK

 

(R8, C3) 

Master clock of Subharmonicon 

Patch to TRIGGER input to trigger 
notes on every clock pulse regardless of 
RHYTHM settings, or connect to external 
instruments for synchronization. 

TRIGGER

 (R8, C4) 

A trigger output which is sent to the VCF 
and VCA EGs 

This differs from the CLOCK output in 
that it only fires whenever SEQ 1 or SEQ 
2 moves—which will be very different 
from the CLOCK output depending on 
the POLYRHYTHM settings. Connect to 
external instruments, or try connecting 
to VCO inputs, CUTOFF, or VCA for a 
sharper attack transient.
