PianoRollComposer 2.38

PianoRollComposer allows you to compose and play MIDI music. It works by using the standard treble and bass clef staffs, but notes are displayed in the piano roll format, so it shows music with absolute accuracy. Notes are entered directly on the staffs, and you can edit each note to give it the exact characteristics you want. You can input and edit any of 128 MIDI instruments and 61 percussion instruments.
