Basic Operation

The PCM 81 has 5 basic modes of operation, selected by pressing: Program Banks, Register Banks, Edit, Control or Tempo

Program Banks

and Register Banks

Press Program Banks to
cycle through 6 banks of 50
presets. Press Register
Banks to access an internal
bank of 50 registers (or
PCMCIA card banks) where
you can store modified ver­sions of the factory-loaded
presets.

Simultaneously press the
Banks button with either Up
or Down to backstep
through the banks.

Turn SELECT to view all of
the effects in the selected
bank. A ✱ in front of an effect
name indicates that the ef­fect is not loaded. Hold down
either Banks button to see
the name of the currently
running effect.

Press Load/✱ to load any
displayed effect.

ADJUST acts as a soft knob
for adjustment of one or more
patched effect parameters.

Each set of PCM 81 controls
is organized into a matrix of
as many as 10 rows and 10
columns.

Simultaneously press Up

available parameters for the
currently running effect. Turn

tem parameters, MIDI con­trols, and global control of
parameters such as Mix,

the matrix.

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.)

Tempo

Press Tempo to set tempo-
related values that affect the
delay time and LFO rate pa­rameters of the currently
running effect.

Tempo

Any PCM 81 delay param­eter (as many as 10 in some
effects) 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 which are
linked to tempo. When you
change tempo, the delay
times will change to main­tain the same rhythm at the
new tempo.

To set PCM 81 tempo rate,
press Tempo. Use SELECT
and Up and Down to locate
matrix position 0.0. Turn AD-
JUST to select any Tempo
Rate from 40-400 BPM.

Or, press Tap twice in
rhythm to establish the
tempo rate you want. Tap is
always active, allowing you
to change tempo on the fly.

Info

The PCM 81 offers an exten­sive set of informative dis­play messages which can be
activated from the front
panel. If you want to know
more about the function of a
particular button —without
actually executing any ac­tion — press and hold the
button down. While you are
holding down the button, an
explanatory message will
appear on the display.

Edit

The PCM 81 offers two levels of editing control: Go mode and Pro mode.

Go mode gives you access to a specific set of as many as 10

parameters for each of the 300 presets. We have designed
each set of parameters to allow you to make changes to the
effect without losing the character of the sound.

Pro mode gives you access to the full effect edit matrix
whenever you press Edit. The edit matrix contains all effect
parameters, as well as Patching and Modulation controls.

The PCM 81 is shipped in Go mode. To change the Edit mode,
press Control, use SELECT and Up and Down to locate
matrix position 1.0. Turn ADJUST to select Go or Pro.
