[PD] Spore [was: TR909 emulation]

[Andy Farnell]

This is a general feature of procedural audio. In fact Pd plays very nice and has
a fixed (predictable) cost for signal rate graphs - but a variable and 
unpredictable cost for message domain computation.

Proc audio eventually beats sample replay on cost because of dynamic level of
detail where we get a variable (but predictable) cost for dynamically built
signal graphs against a linear fixed cost for sample playback. It's an
interesting bit of computer science to think about.

I know from talks with EA guys that EAPd ran into some problems and its
performance was not spotless. But not for the reasons you state.
