I’ve been experimenting with the trial version of Reason Studios’ Friktion, a physical-modeling synthesizer that emulates bowed instruments such as the violin. All the voices in the “Estampie” above except the percussion are instances of Friktion.
Compared to the Applied Acoustics String Studio, the bowed sounds are more natural, and it’s easier to figure which knobs to twiddle to get the sound you want. However, String Studio handles plucked strings better and is more generally useful.
While Friktion does get closer to a proper fiddle sound than most synthesizers and cheap sample sets, it’s not really convincing. It might work with a bit of reverb in a busy arrangement, but I wouldn’t want to use it solo or with just piano accompaniment. I probably will let the trial lapse and get one of Embertone’s violins instead.
