hi community. i am choosing a sound card for my new box, an i found myself totally obscured about such thing as hardware mixing. so, please help me to clarify: (0) what it _actually_ does? and (1) in particular, (how) can it help in live performance? some details: i'm choosind between echo (mia midi or gina 3g) and m-audio (delta series) cards. the only thing used for live performance is csound driven by hardware midi controllers. thanx in advance. p.s. yes, i did pretty much googling etc before writing here. -- sex, pot, open source!!
