Table of ContentsGuitar MIDI Controller to NotationInitial NotationThe 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. Remove Spurious NotesGuitar controllers are a bit finicky and tend to generate spurious notes. We can clean this up quickly using Rosegarden's Event Filter dialog.
Configure the Event Filter dialog as follows:
Make sure “Use notation duration” and “Select rests” are unchecked. What this says is, “I want all the notes except for the ones that are 1/16th notes or larger.” This will select only the small spurious notes. Luckily, the Event Filter dialog will remember its settings, so this will go more quickly the next time.
Now only the small spurious notes will be selected.
Quantize to 1/4Next we want to make these all perfect 1/4 notes.
Set up the Quantize dialog to quantize to 1/4 notes.
Bring up the segment in Notation to see the improvements. Remove MarksThe notation isn't quite perfect because Rosegarden attempts to interpret a performance and add in tenutos and staccatos. To remove those:
And now we have something that looks like simple notation. Future DirectionNoted 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. |
