Beat and Bassline improvements

The ability to be able to see the size of each note and change position of note.

For example:
You know the regular beat and bassline? Perhaps add something similar to that of the roll for each note.
Instead of the beat and bassline being in quarter notes, perhaps add a feature to display them as 1/8th or even 1/16th notes. This could add variation and make it easier to control where each note is without having to enter the piano roll for the beat and bassline.
The ability to be able to see the size of each note and change position of note. Like a drag mode for the note... or be able to pull down notes from different lines


No source file, test, or entry point is named. Start by locating the beat and bassline editor and its relationship to the piano roll, then determine how note subdivision, size, and position are represented. Done would require a defined interaction that displays and edits these properties, including eighth- and sixteenth-note variations.
