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. The material of the strings can be changed continuously from metal to plastic. The plug-in is based on the same technology as Sylfid-f1, but is less complex to tune. For example the strings material cannot be changed on a per string basis and the hammer position is fixed.
