Basic Operation

The PCM 91 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 9 banks of 50 presets. Press Register Banks to access 2 internal banks of 50 registers (or PCMCIA card banks) where you can store your versions of the factory presets.

Turn SELECT to view all of the effects. 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.

Simultaneously press and release both Banks buttons to view the previously loaded effect. Turn SELECT to view as many as 10 effects back.

Each set of PCM 91 controls is organized into a matrix of as many as 10 rows and 10 columns.

Simultaneously press Up and Down to return to 0.0.

Up and Down move you vertically through the rows of 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.)

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.

Control

In Edit, Control or Tempo mode, a ✱ indicates the presence of multiple parameters within a single matrix location. Press Load/✱ to cycle through all of the param- eters; simultaneously press Load/✱ with either Up or Down to backstep.

Tempo

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

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.

Press either Banks button one push beyond the last bank to view the list of sorted effects. Turn SELECT to scroll through the list.

To set PCM 91 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.

To select a different KeyWord for sorting, go to Control 1.8. and use ADJUST to select any KeyWord from the following list.
