Touch the FILTER tab on the right to access
the FILTER module.
Select a filter TYPE:
• LP is a low pass filter that allows only frequencies
below the cutoff frequency to pass.
• bP is a band pass filter that allows only frequencies
at and around the cutoff frequency to pass.
• HP is a high pass filter that allows only frequencies
above the cutoff frequency to pass.
FREQUENCY: Determines the cutoff FREQUENCY
of the filter. This is the point at which the filter
begins to “work”.
RES: Adjusts the amount of RESONANCE, or emphasis,
at the filter’s cutoff frequency. Lower settings create
subtle colorations of the sound. Higher settings add
strong overtones. At 10, the filter is capable of
self-resonating.
DRIVE: Sets the amount of pre-filter drive from zero to full saturation. This
control is modeled after the classic Moog ladder filter design.
TECHNICAL NOTE: Unity gain is at “5”. Bipolar modulation of the drive control
inverts the signal phase as it passes below zero.
ENV: Works in conjunction with the FILTER ENVELOPE found in the ENV/mOD
page. Positive settings apply the envelope in the normal attack, decay, sustain,
and release manner. Negative settings mean that the envelope is reversed. A
setting of “0” means no envelope is applied.
See the Env/Mod section for information on the Filter Envelope.
