6–2: Amp Mod.
This page contains the settings for Oscillator 1’s Amp level
modulation. Among other things, you can:
• Set up complex keyboard tracking shapes to control the
Amp level.
• Assign AMS modulation for the Amp level.
• Control the effect of the LFOs on the Amp level.
The total effects of the modulation can increase the volume
to a maximum of two times louder than the Amp Level
setting.
6–2a: Keyboard Track
Keyboard tracking lets you vary the volume as you play up
and down the keyboard. Usually, some amount of key
tracking is necessary in order to make the volume consistent
across the entire range.
The AL-1’s Amp keyboard tracking parameters are identical
to the HD-1’s. In both cases, the Amp keyboard tracking
works somewhat differently from the Filter and Common
keyboard tracking. For more detailed explanations of the
parameters, please see “4–2a: Keyboard Track,” on page 76.
There is one difference between the two, however: the AL-
1’s Amp tracking is affected by Portamento, so that it
changes smoothly during glides.
Key
Low Break [C–1…G9]
This sets the breakpoint note between the two lower ramps.
Center [C–1…G9]
This sets the center of the keyboard tracking. At this key, the
keyboard tracking has no effect on the volume, or on any
AMS destinations.
High Break [C–1…G9]
This sets the breakpoint note between the two higher ramps.
Ramp
Bottom-Low [-Inf, –99…+99, +Inf]
This sets the slope between the bottom of the MIDI note
range and the Low Break key. For normal key track, use
negative values.
Low-Center [-Inf, –99…+99, +Inf]
This sets the slope between the Low Break and Center keys.
For normal key track, use negative values.
Center-High [-Inf, –99…+99, +Inf]
This sets the slope between the Center and High Break keys.
For normal key track, use positive values.
High-Top [-Inf, –99…+99, +Inf]
This sets the slope between the High Break key and the top
of the MIDI note range. For normal key track, use positive
values.
