Hi, Sherry, Fred:

That sounds a lot like a conflict over a MIDI port.

Fred, is there any software running that might be grabbing a MIDI port? For instance, Maple MIDI virtual midi ports can't share -- if a second program tries to connect to it, the whole system comes to a grinding slowdown.

I've gone over from Maple MIDI to LoopBE for virtual ports on my new Win7 'umputer.

If you have a previous version of Composer (or any Notation software) on your computer, try deleting MidiDev.cfg from the Notation and Composer directories. Composer will then create a new one on startup.

Good luck.

David
