We have found that some keyswitch-related problems may occur as a consequence of receiving CC#123 (all notes off) midi messages.
CC#123 is outputted by some keyboards and sequencers when no note is being held. This may interfere with proper functioning of the program in several ways, for example affecting the response to keyswitches, and switching off release-triggered notes.
We have therefore modified the script to filter out any CC#123 message.
We'll very soon upload the new version, 1.07, which should be used by all customers, replacing the previous 1.06.
This should solve (at least some) past and future issues.
