PROG 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.
• 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.
4–1: Amp1/Driver1
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
[Off, On]
When
Bypass
is On, the Driver is completely removed from
the signal path.
Drive
[00...99]
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)
[List of AMS Sources]
This selects an AMS modulation source to control the
Drive
amount.
For a list of AMS sources, please see “AMS (Alternate
Modulation Source) List” on page 374.
Intensity
[–99...+99]
This controls the depth and direction of the AMS
modulation for Drive.
Low Boost
[00...99]
This low-frequency EQ controls the body character of the
sound. The specific EQ frequencies affected will change with
the
Drive
setting.
Higher amounts increase the bass boost, and will also
intensify the effect of the
Drive
parameter.
AMS
[List of AMS Sources]
This selects an AMS modulation source to control the
Low
Boost
amount.
For a list of AMS sources, please see “AMS (Alternate
Modulation Source) List” on page 374.
Intensity
[–99...+99]
This controls the depth and direction of the AMS
modulation for
Low Boost
.
4–1b: Amp Level
Amp Level
[000...127]
This controls the basic volume level of Oscillator 1, before
keyboard tracking, velocity, and other modulation.
The OSC/DrumTrk Mixer and volume
You can control the Oscillator volume directly from the
sliders in the 0–4 OSC/DrumTrk Mixer page. This is a
separate parameter, in addition to
Amp Level
.
MIDI and volume
You can control the Program’s overall volume via MIDI
using both Volume (CC#7) and Expression (CC#11).
When used one at a time, the two controllers work in
exactly the same way: a MIDI value of 127 is equal to
the
Amp Level
setting, and lower values reduce the
volume.
If both CC#7 and CC#11 are used simultaneously, the
one with the lower value determines the maximum
volume, and the one with the higher value scales down
from that maximum.
This is controlled on the global MIDI channel (Global 1–1a).
