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