MIXER
The mixer allows the levels of all six Subharmonicon 
sound sources (VCO 1, SUB 1, SUB 2 and VCO 2, 
SUB 1, SUB 2) to be set individually to create the 
perfect mix. The combined signal is sent from the 
mixer to the filter for further sound-shaping. (This 
section is also home to the quantize and sequencer 
assign functions.)
ENVELOPES
Two envelope generators define how 
the sound changes over time. The VCF 
EG controls the attack time and decay 
time of the filter (VCF); the VCA EG 
controls the volume (VCA). 
PATCHBAY
This patchbay offers 32 connections 
(17 inputs and 15 outputs) for connecting to 
other modular or semi-modular synthesizers 
and audio equipment. MIDI data can be received 
at the MIDI IN jack using the included Type A 
MIDI adapter at the MIDI IN jack.
TEMPO & TRANSPORT
The tempo drives the rhythm generators, which in 
turn drive the sequencers. The transport controls 
start and stop the sequencers, advance to the 
next step, and more.
SEQUENCER
Sequencer 1 controls VCO 1 (and its subs). 
Sequencer 2 controls VCO 2 (and its subs). 
Each sequencer has four tunable steps.
RHYTHM GENERATORS
Dividing the tempo creates a new rhythm. 
Each of the four rhythm generators can drive 
one or both sequencers. Combine rhythms 
for exciting polyrhythms.
OSCILLATORS
Two analog oscillators (VCO 1, VCO 2) form the 
foundation of the sound. Change the waveform to 
select a new timbre. Each VCO can be continuously 
tuned over a specific range, or quantized to the steps 
in one of four scales. Two subharmonic oscillators 
per VCO are individually tunable to one of the first 
16 undertones of the VCO’s current pitch. 
FILTERS
The famous Moog ladder filter provides 
excellent timbre control. This VCF operates 
as a low-pass, four-pole (-24dB/octave) filter. 
Resonance control is provided.
