MIXER
The mixer is used to set the relative levels of Oscillators 1 and 2.
VCO 1 knob [0...1023]
VCO 2 knob [0...1023]
These knobs control the output levels of Oscillators 1 and 2.
FILTER
VCF: Voltage Controlled Filter
The low-pass lter shapes the tone by selectively ltering certain parts
of the harmonic spectrum of the sound generated by the Oscillators
and the Noise generator.
CUTOFF knob [0...1023]
This knob is used to set the cuto frequency. Harmonic content above
the cuto frequency will be ltered out.
Turning the knob to the left will lower the cuto frequency, and turning the
knob to the right will raise the cuto frequency.
If the CUTOFF value is set too low, the volume may be extremely
low.
RESONANCE knob [0...1023]
Also known as Peak or Q, the RESONANCE control adds additional emphasis
to the overtones occurring at the CUTOFF frequency, giving a distinctive char-
acter to the sound.
Turning the knob to the right will increase the resonance eect.
TIP
The overtones that are emphasized will change depending on the cut-
o frequency. For this reason, it’s good to adjust the CUTOFF knob
while adjusting the RESONANCE knob.
When emphasizing the overtones in this way, the sound may distort
depending on the cuto frequency or the input audio.
