●Program Change

Works as program change for the effects when MIDI channel number is set to 0H, 1H, 2H or

3H. Works as scene switch when channel number is set to FH. VS-1680 never transmits this

message.

Status Second

CnH ppH

n = MIDI Channel No. : 0H - 3H ( ch.1 = EFX1, ch.2 = EFX2, ch.3 = EFX3, ch.4 = EFX4 )

FH ( ch.16 = Scene Memory (*1) )

pp = Program No. : 00H - 63H (0 - 99) n = 0H, 1H

pp = Program No. : 00H - 07H (0 - 7) n = EH

(*1) If received while VS-1680 is playing, playback stops, and then restarts after the scene

switched. Never receives while recording.

●Pitch Bend Range

Receives when effect algorithm 27 (Voice Transformer) is selected and MIDI Control SW is On

Status Second Third

■System Common Messages

●MIDI Time Code Quarter Frame Messages

MIDI Time Code Quarter Frame Messages can be transmitted while the VS-1680 is running

(Playing or Recording) if the SYSTEM parameter “Syn:Source” is “INT” and “Syn:Gen.” is

“MTC” in the SYSTEM parameter. The transmitted time counts are summed to “SMPTE

(MTC) Offset Time” as the song top is “00:00:00:00.” The VS-1680 synchronizes with the

time counts which are summed to “SMPTE (MTC) Offset Time” as the song top is

“00:00:00:00” if the SYSTEM parameter “Syn:Source” is “EXT.”

Status Second
