change all the 16th notes in the bass to half notes
Ok I managed to import a midi, merge the staves, transpose the notes into right key, increase the system distances, (just about everything I asked how to do in the past in here.) and now I have a readable
but the original midi i used has wrong durations for the bass notes. I need to change all the 16th notes in the bass to half note duration.
How do I do that except to do it manually one at a time?
