I still don’t think I’m building the correct Sysex message to change the source instrument.
The root key for the parameter I’m trying to set is 0x200, the type key value is 68 (this appears to be decimal). Should I convert 68 to hex, which is 44 and add it to 0x200 to get 0x244?
If this assumption is correct then the Sysex message to change the source instrument to bass would be;
F0 – Sysex start
1C – Eventide
70 – H4000
02 – midi channel 2
3C – SYSEXC_USEROBJECT_SHORT
32 – ASCII 2
34 – ASCII 4
34 – ASCII 4
20 – ASCII space
F7 – Sysex end
F0 1C 70 02 3C 32 34 34 20 31 F7
Byte Parameters:
type key value is tj_sysvars_byte_key (TJ_ROOT_KEY+0x200)
68: sp_instrument 0: guitar, 1:bass
