Internal Parameter List - Yamaha REV500 Operation Manual

Internal Parameter List

This section contains lists of the internal parameters for each effect type, together with a block diagram
illustrating how the effect works. Since it is also possible to control internal parameters in realtime using
MIDI Control Change messages, the corresponding controller numbers are also included in the lists.
