Aha! Yes, this is much better! And, since the same code is (I guess) used
for both MIDI and audio files, it's fixed for both at the same time :-)
(I remember having seen that issue before, and that was when creating&using
groups of audio files).

Thanks a lot, and "SELB++" if you know what I mean ;-),
