Sylfid-f2 is a new physical modeling string plug-in that
models a musical instrument that has two strings per note.
It doesn't use any samples: everything is computed using
a fast simulation algorithm. It computes the propagation
of waves on the strings, and converts them to sounds in
real time. This allows creation of sounds that exhibit
real-life properties like long decays, without any
samples, no loops and no reverb.
