Forgot to mention, you have to bang the tube length message in each waveguide delay line to get the FIR's functioning, haven't sorting this issue yet either.

Hello community, Having troubles getting my waveguide to function properly and I think the issue lies within the scatter junctions. Anyone up for taking a look? The waveguide is based on maarten van walstijn's piecewise design if you're familiar. Cut a long story short, pulse-chebyshev creates the nonlinear pressure fluctuations, the mouthpiece is modelled as band pass resonator, the resultant sections waveguide delays, FIR fractional delay and lop loss filters. The bell reflection is at the moment generalised as a lop and hip filter as I am experimenting with the [partconv~] object. Conical waveguides such as the back bore and mouthpipe are modelled as tubes of average radius with amplitude and frequency losses lumped at the ends. Anyway, the files attached in the email. See what you can make of it.
