B4 II – 23
In this screen shot, note that Creamware’s ASIO control panel simply lets you
choose the desired latency; buffers are adjusted “behind the scenes” within
the Creamware Scope application (in this case, to 128 samples). The Device
Setup panel in Cubase confirms the latency, which is about 4 ms, but doesn’t
indicate the buffer size.
Warning: Different Types Of ASIO
It’s extremely important to use the ASIO driver written for the card you’re using.
There are also “generic” ASIO drivers, typically called (for Windows) “ASIO
DirectX Full Duplex Driver” or “ASIO Multimedia Driver.” They will usually be
found in a drop-down menu in the host program where you choose the desired
ASIO driver. If you’re not sure which one to use, try them all, and choose the
one with the lowest latency. There should be an obvious, dramatic difference
when you use the correct ASIO driver.
