> What is the usual technique for simulating plucked strings?
As already mentioned in the thread, additive synthesis can be used for this. Here is an example using only sinusoidal oscillators: http://www.freesound.org/people/jaiserpey/sounds/165444/ The key is the amplitude envelopes used for each oscillator. In the example above I used Cellular Automata to generate those amp. envelopes, using also a technique for sound design called Histogram Mapping Synthesis (HMS). A recent paper about the HMS technique has been published in the Computer Music Journal. In the link above there is a conference paper explaining the technique especifically for the design of plucked string-like sounds.

Interesting, thanks for the info! What is the usual technique for simulating plucked strings?
