-    You are manipulating the mechanical model at haptic rates 0-10 Hz, and independent to this, you are scanning out the wavetable at the pitch frequency. Although, the table has its own dynamics, there are no discontinuities because the model is implemented as a circular string, so you end up with a 128 point looping oscillator with a constantly evolving loop. It is hard to believe, but true, that what results is a short sample that is animated and harmonically rich because of the complex interactive nature of the elements in the underlying system — the mechanics of the model.
