The 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
.20 dB louder than C 4 if triggered with the same attack velocity. If the value for this parameter
were negative, C
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.
