[sdiy] analogue physical modelling organ dream

[JH.]

I have approx. fifty  512-stage BBDs, so I could build 4 octaves of a fully
polyphonic
instrument. This _must_ work with one BBD per note.
The simple nonlinearity I've tried so far, doesn't give good results,
though.
I think of using a Serge-style wavefolder for the nonlinearity now.
At the moment, I just start to test the concept with a monophonic
instrument.
