Guitar MIDI Controller to Notation

The initial notation that Rosegarden generates from a guitar MIDI controller looks like a complete mess.

But what we want is hiding in there. It just needs some post-processing. In the Matrix editor we can see that things aren't too bad.

Samples provided courtesy of Mike Knott.

Rosegarden's Quantize feature can turn these into perfect quarter notes.

• Press Ctrl+A to select all notes.
• Press “=” to launch the Quantize dialog.

Set up the Quantize dialog to quantize to quarter notes, remove notes smaller than sixteenths, and remove articulations.

• Click Ok to quantize.

And now we have something that looks like simple notation.

Noted some issues while going through this…

The event filter dialog fields should be ordered:

The current ordering with “include/exclude” on the front is odd. Sure, it kind of reads like English, but it is unclear.
