I'm no producer, more like a student, and am trying to transpose a 4-note midi section from Bb to Ab. Working with Rosegarden I first of all tried to let Rosegarden do the honours. The result ended up sounding bad, advice obtained elsewhere suggested that I do it manually. I tried that too but the result still sounds bad.

The section is on two tracks so in the image the original tracks in Bb are the two on top, the attempt to transpose into Ab are the bottom two. The staff in both cases is C to force explicit accidental notation regardless of key.

Is this because the notes in question happen to be chords? I've read somewhere that chord transposition involved some other footwork especially in the case of accidentals?

Hmm, ideally you just select all notes in matrix editor and move up 2 semitones. There shouldn't be any problem. Any MIDI editor should work.

I don't know exactly what you did, but your transposition is wrong. The third measure should be a Db major in the key of Ab. But you've got an E note in there. Looks like a human error. Change that E to an F note.

Use rosegarden's transpose function instead of doing it manually.

This is what I do in Rosegarden all the time. Never had a problem with it yet.
Select all, or just the notes I want to move, then up/down arrow. Shift moves it an octave.
