Program Editor—F4 AMP Page
Press the F4 AMP soft button to call up this page, which features five of the six common DSP
control parameters, in this case controlling the final amplitude of the current layer before it
reaches the audio outputs. There’s also a parameter that enables you to pad (attenuate) the
current layer’s signal before its final amplification.

Adjust
Adjust the overall amplitude (gain) of the currently selected layer. In multi-layer programs, this
parameter adjusts the amplitude of the layers relative to each other. This is the final output
control for the layer (Post-amp pad). Be careful not to set this too high! If one of your layers is
too loud, it’s generally better to cut its level than to boost the others. This will keep distortion to
a minimum.
Key Tracking
This uses the MIDI note numbers of the notes you play as a control source affecting the
individual amplitudes of each note in the current layer. Positive values increase the amplitude
as you play higher-pitched notes. For example, if the key tracking is .20 dB/key, then C#4 will
be .20 dB louder than C 4 if triggered with the same attack velocity. If the value for this
parameter were negative, C#4 would have less amplitude than C 4. A word of caution here:
values above 0.30 dB/key (or below –0.30) can generate extremely high amplitude levels. If you
set this parameter that high without lowering the value of the Adjust parameter to -12 dB or
lower, your sound may clip, which can be useful, but it isn’t necessarily what you want.
Velocity Tracking
This uses the MIDI attack velocity value of the notes you play as a control source affecting the
individual amplitudes of each note in the current layer. This is the primary parameter to use for
adjusting the dynamics of a layer. At a value of 0, every note in the current layer would have
the same amplitude, regardless of its attack velocity. When the value is positive, note amplitude
increases as attack velocity increases. When the value is negative, note amplitude decreases as
attack velocity increases. Larger values increase the range between minimum and maximum
