It would be really fun to have the controller send random values for a given CC#.
Example: on the Tonal Recall, you could send random values to CC# 17 (time) to create some pitch shifting effects (as opposed to using an expression pedal where sweeping through a range of values creates more of a rubberband effect).
The implementation could work something like this: select the CC# and the range of values you want to randomize between. So in the above example, maybe you don't want to select every value between 0 and 127, but maybe just half of the range, between 64 and 127. And maybe it could work like a toggle, where you have a default CC# value when "inactive", and when you step on the toggle the randomizer then starts between the range of values you enter.
