I've updated my Kemper workflow which seems like a good compromise to me. I know have just 2 button pages and make use of hold functions on the top row of buttons. Normal push toggles on and off Stomps A - D while Hold on each of those toggles on X - Rev. The only slight compromise is a small delay on the A - D stomps while the PBS waits to decide if it is a single push or a hold command. However, If I want an absolutely instant switch I can just change to a new Rig in the performance slots.
Page 2 now turns on/off tuner, steps through Expression pedal functions (somewhat redundant though as I have the Wah>Volume and Wah>Pitch enabled in the KPA itself). It also contains Bank Up/Bank Down and output A/B on off. The outputs are only used if I'm trying to do an A/B comparison between my original amp and the profile after the profiling process has been completed. Again it's probably redundant but at the moment I am still in that phase where I want to know if the Kemper really does sound and feel exactly like the real amp through a cab.
All of the preset names and performance names sync perfectly between the PBC and KPA
@rjmmusic - I have one problem though.
When I use the External Buttons for Bank Up/Down everything works perfectly BUT I can't rapid scroll by holding the buttons.
If I use the Bank Up/Down buttons on the PBC itself rapid scroll works BUT banks don't load on the KPA - it sits waiting for a preset command.
When I enable Instant Bank Switching on the PBC, Kemper Performances load on the KPA BUT Bank UP/DOWN now steps through KPA performance slots individually rather than in banks of 5.
If I disable Instant Bank Switching the external Up/Down buttons work as normal (except there is still no rapid scroll) but the Bank Up/Down on the PBC scroll to the correct KPA performance and wait for the instruction to load the first preset/slot. However, when I toggle back to my preset page and press button 1 it cancels the new performance bank and reverts to the previous bank. I thought this might be due to the intermediate step of toggling button pages so put a load preset 1 button on button page 2. Unfortunately, I got the same behaviour. I thought this might be a bug in the most recent Kemper O/S so rolled it back to the last official release but got the same results.
Any ideas Ron?
