3.1 Scene change
A scene change uses a bank change followed by a program change.
Bank
Program
BN 00 BK
C0 PG
Where: N= MIDI Channel, BK = Bank, PG = Program
The bank change (BK) selects between three ranges of scenes:
Scenes 1 to 128 = Bank 1 = 00
Scenes 129 to 256 = Bank 2 = 01
Scenes 257 to 300 = Bank 3 = 02
The program change (PG) is then a value between 00 and 7F (decimal 0-127),
which selects a scene in that range.
 Note that there is an offset of -1 between the SQ values and the MIDI values due to the
SQ counting from 1 to 128 and MIDI counting from 0 to 127.
So scene 96 is bank change 00 (1) and program change 5F (95) and scene
264 is bank change 02 (3) and program change 07 (8).
The scene being recalled must exist as a saved scene in the SQ, blank
scenes cannot be recalled.
Examples:
Scene, MIDI Ch

Scene 7, Ch1
B0 00 00 C0 06
Scene 120, Ch1
B0 00 00 C0 77
Scene 156, Ch1

Scene 156, Ch3
