Thanks for the info. That's a shame. I understand that Composer has a load of additional features and needs to have to make it a viable upgrade to Musician, but a limited feature of sticking a dummy or rest measure at the start of a piece in Musician wouldn't really detract from what Composer has to offer - it isn't so much something to allow for composing as to allow for cleaning and preparation of a midi file (in the same way as are deleting erroneous notes and moving notes to more appropriate staves for LH and RH). Might be something to consider adding in future versions for convenience (though tbh it might be that I'm in an odd minority experiencing the problem of midis losing their first couple of notes in some files when played on my Yamaha lesson mode - I do have a fairly old keyboard, a DGX-505).
