I have a Roland RPC-1 R-Bus card, and have a chance to pick up an M-Audio R-Bus card. I know that M-Audio built the card for Roland. Both have the R-Bus connector, but the M-Audio card also has a 15-pin connector, which connects to a cable terminating in 6 RCA female connections, plus another (BNC?) connector.
Does anyone know what the OTHER functions are for the M-Audio card besides feeding the R-Bus?
Is the M-Audio card significantly higher in value/utility than the Roland version?
Are drivers (or a program needed) for the M-Audio card to work?
(The current owner has neither).
