PianistEnvy, a digital piano application for Mac OS X and Mac OS 9.
The software leverages Quicktime to provide you with a range of different instruments which you can play either by pointing using your mouse and cursor and clicking, or through the Mac’s keyboard itself.
PianistEnvy emulates 120 different instruments through QuickTime, include a 60 piece drum kit. You can play more than 80 notes for each instrument, and use Octave, Pressure and Duration controls to manipulate how each note sounds.
