Hi Larry,

Thank you again for your input.

I have not yet approached PG Support on this one as I was first hoping to establish whether it is a uMIDI/022 or PowerTracks problem. My gut feeling, unsubstantiated, is that it is uMIDI/022 that is the problem as in experimenting over the last few days with reinstalls and in Sonar I have also now been getting the 'insufficient memory' window.

I have decided to purchase a different USB/MIDI interface, as for the small cost involved I can do without all this hassle to get MIDI working satisfactorily. If,then, MIDI is still problematic, I shall contact Support for assistance. I will also keep you advised either way.

Your advice on this matter is much appreciated.

Regards,

Peter J
