The right half of the filter section.
ENV:
This fader controls the amount by which either or both envelopes
modulate the low-pass filter’s cutoff frequency over time. See
to learn more about the envelope generators.
Use the upper toggle switch to select the envelope modulation source:
• ENV 1:
With this setting, envelope 1 acts as the modulation source.
• 1 + 2:
With this setting, both envelopes act as modulation sources.
• ENV 2:
With this setting, envelope 2 acts as the modulation source.
LFO 1:
This fader controls the amount by which LFO 1 modulates the low-
pass filter’s cutoff frequency.
DDS 2:
This fader controls the amount by which DDS 2 modulates the
low-pass filter’s cutoff frequency. The result can range from subtle textures
to complex, experimental timbres.
The
KEYTRACK
toggle switch allows you to determine whether and to
what extent the low-pass filter’s cutoff frequency responds relative to the
pitch of the notes played on the keyboard:
• OFF: With this setting, the low-pass filter’s cutoff frequency is
unaffected by the pitch of the notes played on the keyboard.
• 1/2: With this setting, the low-pass filter’s cutoff frequency follows the
keyboard pitch in quarter tone steps, resulting in brighter sounding
higher notes. This is how acoustic instruments typically behave, so this
setting can be useful for creating more natural-sounding timbres.
• ON: With this setting, the low-pass filter’s cutoff frequency follows the
keyboard pitch in semitones as you move up the keyboard. This is
useful when using the low-pass filter in self-oscillating mode, as the
pitch generated by the filter then precisely follows the intervals you
play on the keyboard, allowing you to play the filter like an oscillator.
