Does anyone know of any applications which have been or are being developed
which make possible real-time sound mixing and effects processing? I am
aware of the Mixer software (and Csound, Hetro), etc. but those tools aren't
real-time (i.e. mix the sounds or add effects and hear the result dynamically).
I have been told that this is theoretically possible through judicious
use of the DSP but it probably requires driver mods for DSP DMA-in handling
(something which was there in .8). Perhaps someone from NeXT could comment on
this latter issue.
