Program(s): Band-in-a-Box 2011, build 317 -- and RealBand 2011, build 4
OS: Windows XP, SP3, Pentium 4, 2.8GHz
ASIO Driver: M-Audio Drivers
Audio Interface: M-Audio 2496 PCI Card
Results: ASIO sputters and clicks for me in BIAB 2011. It worked fine until V. 2011. Had to switch to MME. No problems encountered with MME drivers in BIAB 2011. Can drive CPU to 80% with no problems with MME. ASIO starts sputtering and clicking at 40% -- ASIO works fine in RealBand. Latency is about 12ms. Cannot use more than one ASIO program at once (as expected with ASIO).
