[linux-audio-user] Effects Box --- HARDWARE Type

Greetings all, Jack-Rack with plugins can be used as an effects box for PCM inputs. What about HW inputs? I don't see a way to hook HW1/HW2 on my sound cards to effects programs. The program would be something like a full-duplex record program that would allow capture on HW1/HW2, process in effects rack, then output to PCM1/PCM2 on the same card. Although I'm not very familiar with Cubase, it noticed it allows effects processing of HW inputs before output. Not many programs do this; most process only PCM inputs from what I can tell. Thanks very much for any information. I have external synths and mixer. It would be nice to utilize my spare audio cards as effects processors for the external mixer via Aux send/receive's (both, not just "send"). Dave.
