When editing a loop, imported midi file or existing beat, i get uneven grid with 4 digits above each, how to equally split them into 16th notes?
Berbar, You can try quantizing the beat if its not already quantized.
Alternatively, export the MIDI file and adjust the grid in an external MIDI editor/DAW and re-import it.
Or, you can try an alternate editor I developed, BBFF Editor, that has a MIDI editor with adjustable snappable grid which makes this kind of editing much easier.
Thank you
