VCA DECAY
The VCF DECAY knob determines how much time is required for the Decay
stage of the VCA EG to fall from the level specified by the VOLUME knob
to zero, from 5 milliseconds to 10 seconds. When a trigger is received, the
VCA EG will complete the Attack stage, and then proceed to the Decay stage.
When a gate is received, the VCA will complete the Attack stage and hold at
the maximum level until the gate ends, at which point the Decay stage will begin.
TEMPO
Much of the Subharmonicon performance is derived from the TEMPO setting. This knob sets a base
clock rate that drives the timing of the four rhythm generators, which in turn drives the timing of the
two sequencers.
TEMPO
The TEMPO knob sets the initial clock rate for the sequencers and the rhythm
generators. The range of the TEMPO knob is from .333 Hz to 50 Hz. In the more
musical measure of tempo, this equates to a range of 20 BPM to 3,000 BPM
(Beats Per Minute), assuming 1 PPQ (Pulse Per Quarter-note).
NOTE: An analog clock signal connected to the CLOCK input jack of the patchbay will
override the internal clock and this TEMPO knob. A MIDI clock signal connected to the
MIDI IN input jack of the patchbay (using a five-pin DIN socket to 1/8” plug TYPE A MIDI
connector, such as the one provided with your Subharmonicon) will override both the
internal clock and any analog clock signals connected to the
CLOCK input jack.
NOTE: Internal clock is 1 PPQ until a MIDI clock is detected. When MIDI clock is present,
the PPQ is 4 (16th notes).
