This is a nice discussion about ASIO and MME but the SD50 is a hardware synth, it connects via USB, it's own soundcard so there is basically no latency. The audio is coming out of the SD50, not the computer. It comes with a Roland driver that gets installed and you select that in Biab.

Many people will finally get tired of messing around with all these latency settings and switch to a hardware synth. The only downside with hardware is you can't do a fast render to digital. If you use a softsynth that render only takes maybe 15-30 seconds for a 4 minute song but with hardware you have to route the audio back into the computer and record it in real time so a 4 minute song takes 4 minutes to record to digital.
