[sdiy] Much progress on Buchla waveshaper analysis

[Aaron Lanterman]

Thanks to everyone for their help - I finally cracked (I think) how the 
CA3160's were being used.

Anyone out there know what the total end to end nonlinearity is supposed 
to look like? In particular, does it look anything likes:

Anyone actually heard a Buchla 259 in person? If so, do

users.ece.gatech.edu/~lanterma/buchla_timbresweep.png
users.ece.gatech.edu/~lanterma/buchla_symmetrysweep.png

sound like someone sweeping the timbre and symmetry controls, 
respectively?

(Based on seeing a spectrogram, there's a wee bit of aliasing going on in 
my simulation, but anyway)...

- Aaron, who should have gone to bed hours ago, but couldn't until he got 
this hammered out
