[sdiy] Buchla Model 148 Harmonic Generator

[mark verbos]

Hi Tim,


This is one of the more rare Buchla modules. I have used one.  The  
waveshapes are pretty distorted. There are trims for each of the odd  
numbered harmonics and for each sine shaper, but it's impossible to  
get them really clean. It is really nice for making melodies by  
switching in and out harmonics from a sequencer. I have considered  
doing a version of this using the clipping stages Buchla used in the  
259 timbre section. I think they are more predictable than the diode  
clippers he used.
