Effects Algorithms - Kurzweil PC88 Musician's Manual

Appendix D

Effects Algorithms

The following table shows the effects algorithms accessible on the PC88 either with or without the VGM board in-
stalled. If the VGM board is installed, two different effectsÑInternal and VGMÑcan be used simultaneously.
Algorithms are chosen by sending a specific MIDI Controller message. The value (second data byte) of the controller
calls up the algorithm as listed in this table.
To select the Algorithm for the Internal effects, use Controller 83 (53H), followed by the value in the table. Example:
If you want to have a Bright Hall reverb with no other effect, send Controller 83 with a value of 77 (4DH).
To select the Algorithm for the effects on the VGM, use Controller 90 (5AH), followed by the value in the table. For
example, if you want to have a Normal Room reverb with Chorus 1, send Controller 90 with a value of 86 (56H).
