PITCH
We used the PITCH control-input page as an example to introduce the common DSP control
parameters in Chapter 6 (Common DSP Control Parameters on page 6-14), so we won't add much
here. The PITCH function modifies the pitch of the layer's keymap as it passes through the
sound engine. The PITCH stage of each algorithm is always the first stage. Algorithms 26–31,
the Sync algorithms, don't show the PITCH stage on the ALG page, since these algorithms
generate their own sawtooth waves, and do not use keymaps.
AMP
The AMP function is the final stage in every single-output algorithm, and controls the overall
amplitude (volume) of the layer. This is an easy way to boost the signal to a more desirable level
if it's not loud enough for your purposes. Large values for the Adjust parameter can cause a
sound to clip, which will distort most sounds considerably. You may want this effect, and using
it won't damage anything, but as a rule, you'll want to avoid clipping your sounds with the
AMP (or GAIN) function. There are many other ways to distort your sounds, like DIST,
SHAPER, and WRAP, to name a few.
The settings for the parameters on the F4 AMP page affect the gain level for the currently
selected layer. So do the settings on the AMPENV page. Compare this with the effect of GAIN,
described on page 16-37.
