Mario D,

Thanks for this. Checked MIDI file and is completely 'clean'. Only used either 8 or 24 bar files for test purposes. 32GB RAM, so not overstretched!

However, had a closer look at 'Import MIDI to Melody' options and there is one for 'Setting for # blank bars to insert at beginning', which I'd not really noticed before. Put in a value of '2' and all is well now. Am wondering if this is simply the way the system works, perhaps 'reserving' two bars at the start so it doesn't get in the way of any count-in?
