CAf Range / CAf Cutoff / CAf Amp / CAf LFO Rate / CAf LFO Pitch / CAf LFO TVF / CAf LFO TVA

The other parameters (CAf: 7 types / PAf: 11 types) can be set by transmitting exclusive messages from a sequencer or com- puter. For details on the messages for these parameters, refer to MIDI Implementation p.198.

Using MIDI to control the depth of a System Effect

Reverb / Chorus / Delay

The depth of the System effects Reverb / Chorus / Delay can be adjusted for each Part using control change messages (p.132)

Reverb Send Level

(Controller number 91)

Chorus Send Level

(Controller number 93)

Delay Send Level

(Controller number 94)

The Reverb / Chorus / Delay effects use a portion of the sound from each Part to create a new effect sound (reverberance, etc.) which can then be added to the original sound.

The above three parameters control the amount of the sound (signal) of each Part that will be sent to the effect unit. Higher settings will increase the amount of the signal that is sent to the effect unit, causing more effect sound to be produced. The result is that the effect will be deeper.

Equalizer

The equalizer modifies the tonal character of the sound. You can specify whether or not the sound of a Part will be passed through the equalizer; i.e., turn the equalizer on/off. Settings are made using exclusive messages, not control change mes- sages.
