With all respect for your incredible abilities and demos, I would take 
issue somewhat with what you are saying.  Certainly it is true that you can 
make any waveform starting with a sawtooth, if you have enough filter 
power.  But using just two or three filters you certainly cannot "create 
any sound imaginable".  I have found it much more efficient and effective 
to have a greater palet of starting waveforms rather than just the usual 
trio.  As just one example, a double-pulse waveform can produce a 
high-harmonic-content, odd-harmonic-only waveform that's quite hard to get 
from a square wave.  Used here, for example:
