Thanks for the reply. I've only used the drag drop method to place the files.
The files are non repeating 8 bar patterns. It works fine if I just repeat part of the file but that rather defeats the object.
I checked the base octave for pitches setting which was at 0. I've dropped it 3 octaves but the midi notes still reach G7 half way through the 6th bar and all the following notes are pushed onto G7, which doesn't sound great.
Transposing it down an octave just changes the pitch, it doesn't move the midi notes.
Thanks
