Use SYSEX to control various Parameters on the Kemper

Hello folks,

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,

thanks

Klaus

From MIDI Parameter Documentation (Rev. 149) :

Quote

With 4.0.0, Delays are part of the stomp types. Addressing them will result in no action.

Quote

~~Delay (Address Page 74)~~

Stomp DELAY (Address Page 60)

The parameters are like in Stomp A (Address Page 50) so volume could be the 06 not 04.

Tip! :

Use UI-> MIDI function to monitor desired parameter NRPN using some MIDI monitor software.

Ah, thanks, must have missed that, found the ui-> MIDI in SYSTEM settings, open stage control monitors nicely in and outs, so i should see it...

Thanks again for your help!
