EXPLORING YOUR SUBHARMONICON
(Continued)
EXPLORING THE FILTER
As your sequence continues to play, you can rotate the
CUTOFF and RESONANCE knobs and listen to how changing
the filter settings can affect the timbre of your sequenced
sound. The
VCF EG AMT knob defines how much effect the
VCF Envelope Generator (VCF EG) will have on the filter
settings. By turning the
RESONANCE knob toward maximum
and experimenting with the CUTOFF knob, you can coax the
filter to “chirp” as it approaches a self-resonant state. Try it!
CHANGING THE WAVE
As you explore the ways different filter settings affect the timbre of each note,
you can also use the
VCO 1 WAVE switch to hear how different waves affect the
overall sound.
TWEAKING THE ENVELOPES
As your sequence continues to play, you can change the
Attack and Decay rates for both the VCF EG and the VCA EG.
The VCF EG changes the Cutoff Frequency of the Voltage
Controlled Filter (VCF) over time; the VCA EG changes
the Voltage Controlled Amplifier (VCA) setting, or output
volume, over time. Using relatively quick attack and decay
rates can be best for percussive effects and punchy basses
or leads. Slower decay times can add more of a drone or
atmospheric feel to the sound.
And don’t forget, the VCF EG AMT knob is bi-directional,
with the center position creating no effect. Rotating the
VCF EG AMT clockwise adds a positive amount of envelope
control, while rotating this knob counter-clockwise adds a
negative amount of envelope control, creating some very
useful and unusual effects.
