The Windows version doesn't have code to open multiple cards anyway.
However, the number of channels is passed directly to the MME driver, so
that if a real multi-channel card is available, Csound should be able to
use it up to as many channels as they both support. I will be trying
this very thing out at home soon, using the Creamware Pulsar.

As latency is generally determined by buffer sizes in bytes, it may be
somewhat better for quad streams and higher, than it is for mere stereo.

I understand that m/c drivers are planned for Linux, for cards such as
the Sonorus STUDI/O - but how imminent they are, I don't know.
