frequency of the filter for the selected oscillator. The
way in which the cutoff frequency is affected by the
keyboard location you play can be specified by the
“Tracking Low”, “Tracking Hi

“RampHigh”parameters.

Here is how cutoff frequency is affected by keyboard
location
and the Ramp setting (“ Intensity to A” and
“IntensitytoB”=+50):
Ramp Low
Ramp High
If “Intensity to A”and “Intensity toB”are set to +50,
“Ramp Low” is set to –62 and “Ramp High” is set to
+62, the angle of the change in cutoff frequency will
correspond to the keyboard location (pi tch). This
means that the oscillation that occurs when you
increasethe“ResonanceA”wil
lcorrespondtothekey‐
boardlocation.

Tracking to A/B
These parameters specify the note numbers at which
keyboard tracking will begin to apply, and set the
“Intensity to A” and “Intensity to B” parameters to
specify the depth and direction of the change applied
tofiltersAandB.
For the range of notes between “Key Low” and “Key
High”
, the cutoff frequency will change according to
thekeyboardlocation(pitch).

High Pass
This filter cuts the low-frequency range that
lies below the cutoff frequency. By cutting
the lower overtones, it lightens the tone.
