■EXPLANATION OF VOICE NO. INDICATIONS
When the system is rising in TEST MODE, the VOICE
number is indicated on the LCD in "PLAY MODE".
Example: When the VOICE No. is "1"
SYSAP01:TEST-1
VOICE No. 1
(Set MIDI PGM CHANGE MODE to "OFF" or "MODE
3".)
If this is not done then the second digit of the LCD in
dication will go off.
The VOICE numbers are 1 to 8. Every time the first gate
turns ON, the indication changes.
• When this function is being used, make sure that
system loading is not done by program change by the
MIDI.
