Synthesis types that lends itself well to string instruments:
- Frequency Modulation and Phase Modulation
- Modal Synthesis
- Karplus Strong Synthesis
I’m quite sure you can do convincing electric guitars and exotic string instruments with Renoise’s new comb filter. I managed to convert dBlue’s tuned filter onto the comb filter and will experiment more on a series of comb filters with slight tuning differences in hopes of achieving something similar to Logic’s Scuplture synth.

Trifonic has a great series on FM as well…
