Hello OldMuso, DrDan, AudioTrack, and MarioD (in chronological order of posts I haven't yet replied to ;-)

Thanks for all your comments and suggestions!

I note that I have three new avenues to explore (if I understand correctly):
- Analyzing my computer's performance via Task Manager (AudioTrack)
- Checking whether or not there's stuttering when I make a MIDI recording with RealBand (OldMuso)
- Checking that my Clavinova CVP 307 isn't creating a MIDI loop because the local control isn't set to Off (MarioD).

I'm currently short on time (I'm an amateur musician with other professional activities!), but I'll gradually run these tests and keep you posted on the results.

Thanks again.
