This is what I want to do. I want to send tracks from the digital out of my roland 16-track to a laptop. I know nothing about this so I'm wondering what sort of connections I need in order to send it over either a spdif or an optical out and have the computer turn that into a wav file or what ever is necessary when using a program like protools. Do I need a certain kind of soundcard to send dgital inomation or is that just for converting analog? Also how would I send it back out of the computer as a digital stream back to the 16-track? Any help would be greatly appreciated. The computer also has a usb port if that matters. Thanks!
