Many thanks...  I just need at the moment a modest home made live recording, so
it's enough to me just a small USB one (stereo) channel sound card.  I plug a
microphone into it and another couple of microphones in the built-in sound card
of the PC, through a special double mono cable.  That way I get two different
audio files, one for the voice and the other for the piano.  Then I merge them
together using Sox, so obtaining a 2-channel final remixed audio file, that can
be listen to from a normal stereo player.  What I want now, and for what I
started the present thread, is, as I said, to keep those three channels
separated and listen to them through three different loudspeakers.  Thanks to
the kind help from you listers, I understand that I need one of those
multichannel sound cards...

Regards

Rodolfo
