percolate physical models...
I have been exploring Percolate's physical models. In particular
the bowed instrument. You can definitely hear the effect the
different parameters have on each sound. But the sound itself
is a little on the flat side. I would like to keep the physical
spectral chractaristics that the model imparts, but also enhance
the sound a bit. Can anyone suggest any ideas for techniques I
might try to beef up the sound and make it more interesting.
Thanks,
Anthony

I use subtle random modulation of these parameters, and I use one for
the left channel and one for the right, with slightly different
parameters - that gives a nice stereo effect, which removes if not all
then a lot of the "flatness" you're hearing.
Also, throw in some subtle delay/reverb/chorus to help make the sound
"sit" well.

Thanks, Andreas I will give it a try.
Anyone else have any ideas?
As Andreas saysm *definitely* add some subtle/random modulation to
the various model parameters. I prefer using scheduled versions of
the STK instruments (in rtcmix~/csound~/chuck~) because it allows
greater control of the param modulation, especially with evolving
envelopes (these are also important to fool with because the way
you move into different oscillatory regions in the models can have
a big effect on the output sound).
Fun sig-processing effects also add a lot; I've been trying out
different filters lately to get a range of different sounds.
And if you really want to get carried away you can go and mess with
the code. Usually when I try that I wind up with oscillating
comb-filter sounds.

oscillating comb-filter sounds? Can you elaborate a little
on this technique. I am familiar with comb filtering, how
does the oscillating part work?

Crank up the feedback on the comb filter to near 1.0 and send in an
impulse (or continuous noise). Most of the STK models roughly work
like this with some filtering added ('waveguides' in Julius O.
Smith's terminology).
