Hi all,
I´m having serious problems with a waveguide Physical Model of a
clarinet I´m building. In fact it is really *out of tune* (though the
delay line uses interpolation) and I´d like to know the most probable
causes. I thought they could be the lowpass in the feedback loop (which
induces some freq. dependant delay, but it doesn´t seem to be so big)
and the waveshaping function also inside the loop. What do you think?
I´d like to know if there is a way to apply waveshaping without inducing

phase delays, or a way to calculate it to compensate for the delay in
the loop.
Thancks in advance!
