Took me a bit of experimentation, but yes I got it to work for 2 devices (FX3 and FM9) in the same string, different Midi ID's of course.
I used the comment markers to separate and get it to work for me. Prob not necessary, but once I started that way it just seemed better to continue
Example, Tempo 110, first is FX3, second is FM9. Works fine here
F0 00 01 74 10 14 6E 00 6F F7 /* . */
F0 00 01 74 12 14 6E 00 6D F7
You would need to use the AX8 ID instead of the FX3/FM9, and of course the checksum will be different. From the Wiki:
- 0x00 Axe-Fx Standard
- 0x01 Axe-Fx Ultra
- 0x02 MFC-101
- 0x03 Axe-Fx II
- 0x04 MFC-101 mk3
- 0x05 FX8
- 0x06 Axe-Fx II XL
- 0x07 Axe-Fx II XL+
- 0x08 AX8
- 0x0A FX8 mk2
- 0x10 Axe-Fx III
- 0x11 FM3
- 0X12 FM9 (I added this one, of course)
