I re-implemented a piano model using the STK, based on the original SynthBuilder patch. Adjustable parameters are string stiffness, brightness, and the amount of detuning. The test program is polyphonic and works with any MIDI keyboard. (There is no GUI, however.)

Software (Source, OS X and Linux, and probably Windows with some tweaking):
