PITCH CORRECTION
Attk (Correction Attack Time) determines how fast
the algorithm pulls you toward scale tones. A value of
0 is essentially off and a value of 100 is instant resulting
in something like the infamous "Cher" effect where the
pitch correction effect is stair-stepped and obvious
when using non-chromatic scales. Usually, values
around 20 yield acceptable results.
Amnt (Correction Amount) allows you to soften the
correction effect. A value of 50% for example will only
pull you halfway toward a correction scale target at the
speed set by the Attk parameter.
C2: Scale display and customization screen
In this screen you can see the current scale and its
active scale tones and make changes to both. The
leftmost soft knob allows you to change the scale. As
you change the scale you can see the active scale tones
for the key you've selected in menu C0. The second
soft knob acts like a cursor to select scale tones and
the third changes the flashing scale note to active
(shown by an "o") or disabled (shown by a "-").
