The piano roll allows to output MIDI notes according to a score.
MIDI files can be loaded by drag’n’drop, either on a scenario, interval, or on the piano roll process directly.
Adding a note is done by double-clicking ; the note can be stretched with the mouse.
When dropping a MIDI file, if Shift is held, the tracks are put in sequence instead of in parallel.
Velocity of MIDI notes can now be changed with Shift+Click - the more saturated the note, the higher the velocity.
