Description

In the piano roll editor, one can input notes with a computer keyboard. I wonder if it is possible to change that particular keymap to whatever I would prefer? For instance, I would like two and two rows to be two whole-tone scales, and the top two rows one octave higher than the two bottom rows. Like this ( ' denotes octave up):

c#' d#' f' ...
c' d' e' .....
c# d# f g a h c#' d# f'
c d e f# g# a# c' d' e' f#'

I first did this in the [virtual midi piano keyboard (C++)](http://vmpk.sourceforge.net/), which allows custom keyboard maps.

Research direction

Start at the piano roll editor's computer-keyboard note input and compare the custom keyboard maps in the linked Virtual MIDI Piano Keyboard reference. Define how users would configure the requested two-row octave and whole-tone layout, then verify that the piano roll accepts the configured mapping.
