Program P4: Amp/EQ
Oscillators 1 and 2 have separate controls for volume
(also called "amplitude," or "amp" for short), pan, and
Drive, as well as dedicated amp envelopes and
keyboard tracking generators. Additionally, both
Oscillators share a three-band EQ.
These pages let you control all of these related
parameters. Among other things, you can:
• Set up the Driver circuit, which adds saturation and
bass boost to the timbre.
4–1: Amp1/Driver1
4–1a
This page controls the basic settings for the Amp/EQ
section. Here, you can:
• Set up the Driver circuit.
• Set the initial volume level.
• Control the pan position and pan modulation.
4–1a: Driver
The Driver adds saturation and overdrive to the
sound, for everything from subtle fattening to drastic
distortion. Unlike an overdrive effect, the Driver
processes each voice individually, so the timbre stays
the same regardless of how many voices are being
played.
The two main parameters, Drive and Low Boost, work
together to create the overall Driver effect. Drive
contributes edge and bite, and Low Boost provides the
body as well as boosting the bass.
Bypass
When Bypass is On, the Driver is completely removed
from the signal path.
Program P4: Amp/EQ
• Set the pan position and pan modulation.
• Control amp level and modulation, including
keyboard tracking, the amp envelope, LFO
modulation, and AMS control.
• Set up the three-band Track EQ.
Note that when the Oscillator Mode is set to Single,
only Oscillator 1's amp, pan, and drive parameters are
active; the pages for Oscillator 2 will be grayed out.
4–1b
Drive
This controls the amount of edge and bite in the
timbre. Low settings will produce mild saturation, and
higher settings create more obvious distortion.
Often, it's useful to increase the Low Boost along with
the Drive.
Note: even when the Drive amount is set to 0, the
Driver circuit still affects the timbre. If your goal is a
completely pristine sound, use the Bypass control
instead.
AMS (Drive)
This selects an AMS modulation source to control the
Drive amount. For a list of AMS sources, see "AMS
(Alternate Modulation Source) List" on page 967.
Intensity
This controls the depth and direction of the AMS
modulation for Drive.
