6 0iii iiii Chain # Unlike some other objects, there is no “current” chain, so the
value 0x7F has no effect here. Normally there are 10 chains
available (0-9). If a RAM card is in place (see the configura-
tion message), then an additional 10 chains (10-19) are
available.
7 0iii iiii Bank for chain
position 0 Any legitimate Bank index. See the Appendix C: MIDI Bank
Assignments. If nothing is assigned to this position in the
table, a value of 0x7F is returned.
8 0iii iiii Offset for chain
position 0 49
9-26 ......... Bank/offset for
positions 1-9
