Resize Notes

Option 1

1. Select all of the target notes.
2. Go to Functions > MIDI Transform > Fixed Note Length.
3. Select a length, and click Operate.

Note 1: I find it easier to leave the default, and then click/drag the notes in the piano roll instead. Note 2: Select & Operate will select all in the region. While I prefer explicit selection, this is a quick option e.g. on a newly recorded MIDI.

1. Right click or double tap the MIDI region.
