hrh999,
I am currently reviewing this with the other Engineers but this is what I have for you towards your questions so far:
(1). Such a document was not published but I am working on getting a (soft copy) made.
(2). Being reviewed.
(3). Insertion being reviewed - however you can press the SAVE/ENTER and EXIT buttons together at the end of each midifile that you play. This will remove any insertions and delete any hanging notes.
Thanks,
AJ
