[alsa-devel] Patchmix-style application for EMU cards

Hello I am working on a graphical mixing/routing application for the Emu10k series of semi-pro soundcards, but I am having trouble figuring out the routing mechanism of the driver, specially the "Multichannel PCM" part. Is there any technical documentation on this card I could read (I haven't found any), or maybe the driver developer can help me out?

Thanks, Camilo.
