Hello,
I've found a 'Program List' for the FA-06.
I note that the GM2 facilities are but a tiny part of the sound facilities available, I'd not wish you to restrict yourself to JUST the GM2 bit!!
The GM2 sounds are selected via Bank Select, but there are two levels to this.
Firstly, once GM2 is selected, maybe via an initial Bank Select:
Controller 0 is MSB and this should be 121 decimal
Controller 32 is LSB and this COULD be 0
Then Program Change 0 to 127 for the base instruments
I'd guess that subsequent instruments could be selected with JUST the PC command, staying with the same bank.
However, at a higher level, many of the basic sounds have alternative/subsidiary/variant sounds available, and these can be selected using the complete command set, but changing the LSB byte from 0 to 1, 2, 3, 4, 5 as appropriate depending on the alternative sounds available. Not sure if the PC command is needed as well in this case, the chart does not say.
So, you could prob select the GM2 bank, and then play a midi file and it would be fairly correct.
In another thread, I was discussing a similar problem regarding the Roland SC-D70 (Sound Canvas), which seems to use a similar bank/select process.
Once you suss out the Bank Select commands, then you can access ALL the units sounds using the numbers on the charts.
