Multitouch and multitimbral instrument for touchscreens (also works with a mouse).
Any number of voices can be played simultaneously.
Each row is a separate instrument, so multiple instances of the same sound can be played.
The triangles are not sensitive near the vertices, allowing whole-note glissandos without lifting the finger.
It plays immediately with a USB MIDI device (MIDI input).
Sounds:
Piano: Steinway & Sons Model B
Harpsichord I: Zell 1737
Harpsichord II: from pjcohen at freesound.org
