To run custom effects! Reverb, EQ, Vocoder, Flanger ... - whatever.

Oh 8051. Was really slow ..., I do not know if this chip provides
enough CPU power to run some effets on it. But since I guess it
doesn't provide fixed or floading point arithmetic programming effects
migh be really hard :-(
A DSP (Digital Signal Processor) normally provide sophisticatted
fixed-point (preferred by me) or floating-point support and are much
faster (the Motorola 56000, I played with, executes all instruction in
one cycle and two of these parallel ...)
