PCM 80 User Guide Lexicon

Editing an Effect With 10 algorithms and 200 preset effects, the PCM 80 gives you a lot to play with right out of the box. An enormous range of editing control is provided for each algorithm, with parameters organized in an edit matrix of as many as 100 main controls. In addition to providing this powerful sound design capability, the PCM 80 is also designed to allow you to customize these controls for your day- to-day editing needs, or to simply use a subset of controls specially designed for each preset.

This section will describe three basic levels of editing, from the simplest "plug and play" method, through the full edit matrix.

The Soft Knob Every preset in the PCM 80 has one or more of its available parameters patched to the front panel ADJUST knob. This Soft Knob provides the first level of editing control. Once you have loaded a preset, simply turn ADJUST to alter the effect.

When shipped, the PCM 80 will power up with the first preset (P0 0.0 Prime

Blue) loaded. The following display will appear:

Controlling the Soft Knob with a

Foot Pedal

If you have a foot pedal connected to the PCM rear panel Foot Controller jack, you can use it to control the soft knob patch. (Note that no MIDI con- nections are required to do this.)

To assign a foot pedal control over the soft knob patches, set both Con- trol mode 3.5 ADJUST and Control mode 3.5 Foot Pedal to the same MIDI Controller. See Chapter 5 MIDI Operation.

Indicates that the ADJUST knob is patched to one or more parameters in the currently running effect. This indicator will stay on even if another effect is selected for display.

Turn ADJUST. The display will change to show the name assigned to the ADJUST patch, and the current value of the patch. Continue turning ADJUST to change the value of the patch along its entire range. The range of ADJUST knob control can be limited in Control Mode, making it possible, for example, to have a range of only 0...1, in order to have the ADJUST knob behave as an Off/On control. Many of the presets have range limits to make them more convenient to use. In some of the presets, the changes effected by ADJUST will be as simple as altering the wet/dry mix. In others, such as the example shown below, turning ADJUST will glide you all the way from a chorusing effect to a reverb effect over the complete control range of 0-127.
