I used a spanish train station announcement sample from freesound.org as a basis for the sampled instrument sound, and put a slight echo on it. The physically modeled instrument is ChucK's "Bowed" class, with a little bit of vibrato and reverb.
I slightly changed the physical modeling part, as suggested by the TA's feedback on part I, to better create a "harmonic" moment in the part where the physical model and the sample are played simultaneously.
The parts of the piece are panned differently, with a rather random panning for the sample slices and a continuous movement for the physical model part.
