EG INT knob
The Envelope Generator (EG) can be used to control the CUTOFF, or Filter frequen-
cy, over time using this EG INT (intensity) knob.
To learn more about the EG settings (p.34, "EG").
With this knob in the center position (0%), no EG is applied to the Filter.
Rotating the knob to the left of center increases the EG intensity, but with the po-
larity of the EG inverted.

DRIVE switch
Sets the distortion effect produced by the drive circuit, in three stages.
0% (switch in the lower position): no drive effect.
50% (switch in the center position): drive effect will be set at half strength.
100% (switch in the upper position): drive effect will be set at maximum.
LOW CUT switch
Trims the low range of the sound via high-pass filter.
OFF (switch in the lower position): no low cut effect.
ON (switch in the upper position): low cut effect is applied.
KEYTRACK switch
Key tracking allows the note played on the keyboard to influence the cutoff frequen-
cy of the filter. This is useful when you want higher notes to have more upper har-
monics, or to appear brighter, than lower notes.
0% (lower position): No keyboard tracking will be applied.
50% (center position): The cutoff frequency will change at half the rate/slope as the
pitch of the keyboard.
100% (upper position): The cutoff frequency will change at the same rate/slope as
the pitch of the keyboard.
