====== Guitar MIDI Controller to Notation ======

===== Initial 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.

===== Quantize to 1/4 =====

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.

===== Future Direction =====

Noted some issues while going through this...

The event filter dialog fields should be ordered:

^             ^         ^ Lowest ^         ^ Highest ^
| Pitches:    | include | 0      | Through | 127     |
| Velocities: | include | 0      | Through | 127     |
| Durations:  | exclude | 1/16   | Through | Longest |

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