i’m playing around in paint mode today on v2.0.1 and have run into a bit of confusion with the clear function which can hopefully be addressed in the coming update. according to the v19 thread here, as of v19 the clear button no longer clears the buffer. in v2.0.1, the clear button does indeed clear the buffer. which is cool! presumably re-implemented after complaints about the disappearance of such a useful function.
and now for the confusing bit: when i map the trigger input to clear and send it a trigger, nothing happens. or rather, something happens, but not the thing that happens when i press the clear button. using a trigger to activate clear only deactivates freeze if it is active, but if freeze is off the trigger does nothing. not sure if this is intended behavior or what, but it is quite confusing as there does not seem to be a voltage-controlled way of clearing the buffer completely. the only way to completely clear the buffer is with a manual press of the clear button when freeze is not active, or a double-press of clear when freeze is active (once to turn off freeze, once to clear the buffer).
even though this seems counterintuitive in my current patch i can see how this “clear freeze only” feature would come in handy. perhaps in a future firmware there could be an additional menu option when trigger is mapped to clear - one which toggles between “clear freeze only” and “clear buffer only” and “clear freeze + buffer” (1st trig clears freeze if active, 2nd trig clears buffer) modes.
