it's great you making creative use of it and all that, really thanks.
re. small problem
yes that's an old known problem and it is specific to mp3 files only, specially the ones encoded in VBR mode.
and it is to stay like so forever long, sorry. however there's one trick to mitigate that: if you import a second time later you'll see that the same mp3 clip will get the correct length, this being so because it can only an worst case estimate if the file is not decoded in full all the way first (eg. to get it's graphic waveform, for instance).
re. wishlist
a so called chord-helper would be an interesting addition indeed; meanwhile you might find it otherwise interesting the snap-to-scale options or quantization modes while on the MIDI editor (cf. View> Toolbars >Scale ... ).
