[sdiy] mixer

[matti]

It's time to make mixers; I'm thinking 4 in 1 out or so, driving andbeing
driven by synthesizers and effects mostly. So, some questions  :

is it enough to simply sum all of the inputs with a summing amp, or must
each be buffered?

must all outputs be bufferes (in the case of more outs), or is the one
summing amp enough?

thanks.
