Just an observation about CC:47 in 2x2 mode:
It is supposed to act over the selected track only (described as “Locks or Unlocks the selected track”), and it does so when track one is selected (I already know it is the only one that can be locked in 2x2 mode).
However, when track two is selected (green), the CC:47 still activates the lock on track one (despite no longer being the selected track), but then cannot unlock it, doesn’t toggle the locked state anymore.
Which creates a twisted paradox.
Of course, the ideal behavior in 2x2 mode would be to lock AND unlock track one regardless of the selected track (since it can only be one of them anyway).
Either that or make CC:41 values 103,104 (select Next/Previous track in 6x6) work for 2x2 mode as well. Currently the only way to re-select track one at this point is to overdub it. Not very practical just to be able to unlock it with CC:47.
Actually both issues would be very much appreciated if they were ever implemented.
