i successfully assigned a program change to a rig, after sending it, the profiler switches to that rig, so midi seems to work (I use open stage control and loop midi).
But when i try to send a sysex string (midi documentiation on page 13:
Example: To set the value of Delay Volume to 50% the controller $4a04 (9476) needs to be set to a
value of $4000 (8192):
-> F0 00 20 33 02 7f 01 00 4A 04 40 00 F7
it does not change the delay volume, but a symbol "SE" can be seen (for a short amount of time).
Any help is highly appreciated,
