This looks very promising, if only the product hadn't been sold out...
Can you further customize what the buttons control and how the lights on the buttons behave?
This would make this ideal for me. For instance, is this possible:
1 - short press: previous rig (no light on the button)
1 - long press: DLY module on/off (no light)
2 - short press: next rig (no light)
2 - long press: REV module on/off (no light)
3 - short press: Tuner on/off (button light up when activated)
3 - long press: Don't know yet
A - short press: previous bank (no light)
A - long press: A module on/off (no light)
B - short press: next bank (no light)
B - long press: B module on/off (no light)
C - short press: NRPN sequence to manipulate Rig Volume to switch between 0 db and +3 db (button light up when boosted)
C - long press: Don't know yet
One more thought: surely the KPP knows the note you are tuning to, even if it can't show it. Perhaps it will be possible eventually to send the note to a MIDI device like this to show on the screen?
