Hey guys. I have Sonar LE 5 (I think...), an Edirol PCR keyboard and a tascam US-122 interface. I just want to work out how I can actually get some friggin sound out of the thing. I don't have any midi cables, so I'm trying to use the USB port on the keyboard.

Keyboard --USB--> Computer

Midi Interface --USB-->Computer ---->Headphones

Can someone please tell me how to set it up so I can get some sound happening? Should I just go and buy a pair of midi cables instead? We used to be able to get it to work with Kontakt or something like that, but the computer had to be wiped.
