Is this is a BIAB problem or a Roland problem?? Any input gratefully received.



It depends. You didn't say if you're running 64 bit or not. I have the Sonic Cell with Win 7 64 bit. Roland has a specific 64 bit driver for the SC and it works well for me. Check their website for the proper driver for your SD50 and your OS. If that still doesn't work then Google and download ASIO4ALL. Lots of folks here use it and it works fine although most DAW pros will tell you you're better off with the native ASIO driver supplied with your hardware.

As an aside the only reason you need ASIO is for live playing or recording with a midi controller like a keyboard with other prerecorded tracks from within a DAW, in this case Biab or RB. ASIO is needed to reduce the delay you would hear or see on the screen like the notes on the piano display. If you're not doing that then you don't need ASIO anyway, stick with MME. ASIO stresses a computer even a high spec one depending on how many tracks you're processing along with effects plugins and the like. It can be a very tricky subject to discuss.
