Ma-K: That is a problem, ain't it? With this code, I'd put pairs or series of short notes inside the commas. So 7, would be one long note and 77, would be two short ones or ,7777, would be four shorts. Or could use a back slash (\) to designate where a short note is coming, say: \78 would mean a short note at fret 7 is followed by a long one at 8. Another option would be to give the time signature and set off each measure with two dashes --. If you wouldn't mind, post the names of a couple of the tunes this has been a problem with and I'll see if I can work one of them out.
