I have a DIGI 001 running PT V 6.4 in Windows XP (service pack 1) and I get the following error message when starting up PT: An Error (-1) ocurred while initializing OMS. You may continue without OMS functionality. This is the reason, I believe, I'm having so much trouble getting MIDI to do anything. If anyone can help resolve this OMS error message I'd be hugely grateful. Thanks you in advance.....Chris

Read I beleive it holds the solution to your problems.

Then you should read: (this one may be what you are looking for) and possibly a few others.
