Thanks Bob I am already a member at Music Player and Sonikmatter. Most of the complaints are about editing bugs, not so many re the USB midi issue. It may even turn out to be something making a call on the same resource as the one being used by the USB midi yet..I am still to fully investigate...just making some queries JUST in case others with a PC3 have experienced it.

Re your last sentence, I came to the same conclusion after some tweaking here and there
