Yes, you will need aspi32 for XP available from Adaptec. They work fine on my system TR3A, XP Pro SP2; tested with Audiocatalyst 2.1
Get the files here:
ftp://ftp.adaptec.com/software_pc/aspi/aspi_471a2.exe
You’ll need to install it from the command prompt / cmd.exe. Just double clicking on the install.bat file won’t work, as it requires a parameter to specify which layer to install; 32bit or 64bit XP drivers.
* cd\adaptec\aspi
* install.bat XP32
It will add the registry entries and copy the driver. Reboot and the aspi layer will be available to any apps that require it.

Matt.
