Moog Subharmonicon, Manual

Inputs | 13

VCO 2 

(R3, C1) 

Controls the frequency of VCO 2

See VCO 1.

VCO 2 SUB

(R3, C2) 

Controls the subdivision frequency 
of both sub-oscillators of VCO 2

See VCO 1 SUB. 

VCO 2 PWM 

(R3, C3) 

Controls the pulse-width of VCO 2

See VCO 1 PWM.  

CUTOFF

(R4, C4) 

Controls the cutoff frequency of the filter 

Connect a SEQ here for timbral changes 
per-step, or a VCO or VCO SUB here for 
filter FM. 

PLAY

 (R5, C1) 

A rising gate signal here will be akin to 
toggling PLAY On—a falling gate signal 
akin to toggling PLAY Off. 

Use the VCOs and VCO SUBs for audio rate 
sequencer stopping and starting, or connect 
external gear here to engage PLAY. 

RESET

(R5, C2)

A rising gate signal here will reset the 
sequencers and hold them until the gate 
goes down.

This is mostly useful with external gear 
and sequencers, but play around with 
plugging the SEQ 1/2 CLKs in here. 

TRIGGER

 (R5, C3) 

A rising gate signal here will trigger both 
the VCF and VCA envelope generators—
akin to pressing the TRIGGER button. 

Trigger continued...

Motion in either SEQ 1 or SEQ 2 will 
trigger this input, but you can patch the 
CLOCK here to get faster triggers with 
SEQ 1 and SEQ 2 running at subdivisions 
of the clock. 

RHYTHM 1

(R6, C1) 

Controls the subdivision of RHYTHM 1, 
which is a division of the master TEMPO 
and routed to either SEQ 1 or SEQ 2 via 
its corresponding buttons 

Patch the VCOs (and especially the SUBs 
at low rates) here to get interesting 
rhythmic movement, or patch SEQ 1 or 
SEQ 2 here for further intricate rhythms.  

RHYTHM 2

(R6, C2)

Controls the subdivision of RHYTHM 2

See RHYTHM 1. 

RHYTHM 3

(R6, C3) 

Controls the subdivision of RHYTHM 3 

See RHYTHM 1. 

RHYTHM 4

 (R6, C4) 

Controls the subdivision of RHYTHM 4 

See RHYTHM 1. 

MIDI IN 

(R8, C1) 

A MIDI input to be used with the included 
5-pin MIDI to 3.5mm adapter. For more 
MIDI interfacing information, see manual.

CLOCK

 (R8, C2) 

A clock signal input here will override the 
master clock set with the TEMPO knob. 

Experiment with routing the VCOs in here 
and modulating them for wild audio-rate 
rhythmic possibilities.
