Same here (Play 3.0.20, VEP v4.1.8008) and when trying to change the midi channel within play the play gui crashed and freezed, had to delete the instrument and load again. I'm not a programer so i can't tell but I have had so many bad experiences befor with Play and Logic alone, from crashes to freezes to destroying the whole logic song.
Has anyone so far experiences with Play 2 in VEP? Are the problems caused mainly by the Play 3 update?
