To keep it simple you could store a Rig in your browse pool with amp and cabinet being switched off, assign a progam change number. Receiving this program change # would load that Rig in Browser Mode.
... Can anyone just post the sysex message I need for this? I don't want any explanations about how I can figure it out myself with the MIDI parameter documentation, it would take me at least two or three days which I don't have for try and error in studio ...
That's a bit strange approach in my view ... 
Hi,
as recommended, I start a new thread aboud switching on and off the Stack section via MIDI.
I found another thread which is somehow old...

Hi,
according to (not really elegant)
https://github.com/schoko11/KEKO-…dules/kemper.js
off:
F0 00 20 33 02 7f 01 00 04 41 F7
on:
F0 00 20 33 02 7f 01 01 04 41 F7
where:
F0 00 20 33 02 7f 01 // single parameter set
00 // i think that is off and 01 would be on
04 41 // addy of the stack
f7 // terminates it
hopefully that is right, could not try it out...
Fortunately we have manuals. I'm attaching the current MIDI Parameter Documentation, which is available at the KEMPER download page.
AMP (incl. EQ) and CAB modules can be switched on/off via NRPN. Check out pages 17 and 18.
Amp incl. EQ off
F0 00 20 33 00 00 01 00 0A 02 00 00 F7
Amp incl. EQ on
F0 00 20 33 00 00 01 00 0A 02 00 01 F7
Cab off
F0 00 20 33 00 00 01 00 0C 02 00 00 F7
Cab on
F0 00 20 33 00 00 01 00 0C 02 00 01 F7
I tested with current OS and it works as described.
The receiving MIDI channel of your PROFILER needs to be set to 1 or Omni. Omni is default. In that case it doesn't matter, which channel you select in the NRPN message.
the string is right but it must be written and sent in this order
to turn off
F0 00 20 33 00 00
01 00 0A 02 00 00
F7
turn on
F0 00 20 33 00 00
01 00 0A 02 00 01
F7
This gets you into the NPRN range
F0 00 20 33 00 00
This gets you your address page 11 for the amp stack (0x0A) =0A
0A amp stack
02 on/off
01 00 0A 02 00 00 =off
01 00 0A 02 00 01= on
F7 is at the end of the string.
I used MIDI Wench to get the code
the string must be written as is in the above example
@jojo3110 : are you sure your MIDI interface is handling system-exclusive messages correctly at all ? A lot of (cheaper) USB MIDI interfaces make a mess out of system-exclusive messages. Maybe you could test with NRPN (=regular MIDI control messages) instead ?
example (KPA's MIDI channel set to '1' or 'omni') : send 4 control messages as follows:
AMP on = B0 63 0A B0 62 02 B0 06 00 B0 26 01
explanation:
B0 63 0A = NRPN parameter number MSB (set to 0x0A -> address page = 'Amplifier')
B0 62 02 = NRPN parameter number LSB (set to 0x02 -> parameter = 'On/Off')
B0 06 00 = NRPN parameter value MSB (set to 0x00)
B0 26 01 = NRPN parameter value LSB (set to 0x01 -> switch 'on')
likewise:
AMP off = B0 63 0A B0 62 02 B0 06 00 B0 26 00
note: in 'running status' mode the same messages can be sent as:
AMP on = B0 63 0A 62 02 06 00 26 01
AMP off = B0 63 0A 62 02 06 00 26 00
Screw. the. FUCKING. Interface!!!
How could I have been so stupid and not try it with my MOTU instead of the cheap piece of crap?
This is really the 2nd best community in the world (best is still my family & friends, but of course no one could help...)!!!
Thank you so much for your kind support and patience!!!
If you're ever coming to my town, let me know! There will be beer for you!
