I believe this is usually said about phase within a sound, not realtive
phase which will obviously have audible effects (due to superposition).
You can test this by taking a sawtooth and phase shifting it. It still
sounds like a sawtooth, though it looks like a mess.

I agree. For me another important things about computer music are the infinte
possibilities it offers. Instead of randomly buying new synths I can
code/patch my own and come up with some interesting new sounds.
That said, support for conventional recording is important as a service to
humainty ;) and I heartily support all the amazing work that has been put
in by the 64 frames or bust crowd.
