The Algorithms and Their Parameters

3

The PCM 80 uses ten algorithms to create different types of effects. Each algorithm includes an uncompromised stereo reverb effect, as well as several voices of additional stereo effects. Each of these algorithms and its associated parameters are described in detail in this section.

When you select any effect, the name of the algorithm from which it was derived will appear on the upper display line. Pressing Edit will display the last edited parameter in that algorithm's parameter matrix.

The Algorithms and Their Parameters

The algorithm name appears on the upper line of the display whenever an effect is selected.

All PCM 80 algorithms share the same general structure, shown below. The About the Algorithms shaded area of the diagram is detailed in the individual effect descriptions that

follow.

There are two general classes of algorithm: 4-Voice and 6-Voice. The 4-Voice

algorithms: Concert Hall, Plate, Chamber, Inverse and Infinite each combine a specific type of reverb with a 4-voice, general purpose stereo "effect toolbox" which we call the Reverb Shell. These algorithms also provide "post-processing" for the reverb. The 6-Voice algorithms: Glide>Hall, Chorus+Rvb, M-Band+Rvb, Res 1>Plate, and Res 2>Plate each combine a specific type of reverb with a specialized 6-voice stereo effect.

In this chapter, diagrams and descriptions of the Reverb Shell,and of each algorithm are presented first, along with pictures of each edit matrix. The diagrams are followed by a glossary of parameter descriptions, organized alphabetically by matrix row name. Within each matrix row, parameters are organized as far as possible in the sequence in which they appear in the row.
