Sorry, I use Cubase VST 5.0. I don't know if they are compatible. I get latency down to 10 ms sometimes. It has Directsound, EASI, and ASIO drivers, but I've found the ASIO driver to not work with Native Instruments Reaktor.
Just in case you didn't know already. Seasound has gone out of business. I already own, the Solo EX, and although it has performed quite well (excellent pre-amps), the idea of not having support or driver updates has forced me to look for a replacement interface.
