Your current matrix location is shown in the lower
left of the display. A P, an R or a C preceding the
number indicates you are in a Program, Register
or Card Bank. If there is no number shown here,
you are in Go mode. (See Edit.)

In Program and Register modes,descriptive
bank and row labels appear on the top line of
the display — these can be customized for
your own effects in Control mode.

Effect Sorting

The PCM 91 lets you per­form KeyWord sorting of
your effects. (The default
KeyWord A to Z displays all
of the effects in the box in
alphabetical order.)

As many as 4 KeyWords
can be assigned in Edit
mode to each effect. (We've
already assigned at least
one to every preset.)

Tempo

Any PCM 91 delay param­eter and any time-based
modulator can be individu­ally assigned an absolute
time or tempo value.

Note: You can set and display delay values in units of time, or
with tempo values. Whenever a delay value is displayed in Edit
mode, press Up and Tempo simultaneously to toggle these two
options.

You can set delay times in
milliseconds, or in a ratio of
echoes/beats linked to
tempo. When you change
tempo, the delay times will
change to maintain the
same rhythm at the new
tempo.
