Hi guys,
Unfortunately (and I would also love this!) it’s not possible due to the interrupts required.
We spent some time looking into it, and found that it would negatively affect the speed of other operations and could cause issues.
The MIDI control of Soft Keys actually came about as a solution for this (and of course enabled ‘by-proxy’ MIDI control of many other operations too).
Hopefully we can revisit this sometime though 🙂
Cheers,
Keith.
