*inserting* notes without losing existing notes

Hi folks,

Just started playing around with MuseScore. Started singing in the choir at church a few months ago -- first time I've looked at a piece of music since high school 20+ years ago. Thought I'd see what's out there in terms of music scoring software.

As something to try, I thought I'd see if I could score the first few bars of Goldberg Variation #1 by Bach, since I've listened to the early 80's Glenn Gould recording so many times I've practically worn out the CD, and it's one of the few things I can "hear" from memory.

So, I've put in a number of measures, and find by listening that a note in the middle of things is not as long as it ought to be. I would like to lengthen the note, but by doing so, I destroy notes to the right of it. I totally understand the enforcement of the correct number of notes for the time signature. However, I can see no way to fix the note without having to reenter *all* of the notes to the right of it.

Yes? No?

I'm also a recovering software engineer, so I can totally appreciate the problems with time transposition and pushing things off into subsequent measures, splitting notes (esp. 64th notes!) across measures, etc. Perhaps this is the constraint involved.

If so, any suggestions on how most efficiently to do what I'm trying to do? If I needed to do this in the first bar of a couple hundred measures, and there's no other way, I would be most chagrined, to say the least.

TIA,

Doug
