6-2: Amp Modulation - Korg Electronic Keyboard Parameter Manual

EXi: AL-1 Analog Synthesizer
6–2: Amp Modulation
6–2a
6–2b
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 75.
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
This sets the breakpoint note between the two lower
ramps.
194
Center
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
This sets the breakpoint note between the two higher
ramps.
Ramp
Bottom-Low
This sets the slope between the bottom of the MIDI
note range and the Low Break key. For normal key
track, use negative values.
