[sdiy] SPICE and Processors

[Derek Holzer]

Curtis Roads has a great anecdote about inventing granular synthesis on 
a punch-card computer, and less than a minute also took overnight or a 
weekend to render as well. Somehow I don't think that SPICE is the 
platform for anything near realtime synthesis. For that I recommend Pure 
Data, SuperCollider, Max/MSP, Reaktor... even CSound would render sounds 
out faster ;-)
