Hi Fran

No discernible latency with the Wersi providing you keep within the CPU capabilities, (As with any computer) also the main sound engine used by Wersi is a VST, (Specifically Steinberg’s Hypersonic VST) and is fully optimised with the OS (Win XP for OAS 7 and Windows 7 for Pegasus Wing) to give the best performance possible.

OAS 7 instruments also have a separate DSP card (Which is what the ASIO driver uses) to allow full compatibility with the previous versions of OAS sounds etc. as well as some of the processing for OAS 7. (Pegasus Wing uses a USB ASIO driver that works with the custom Wersi interface board inside)

I am surprised you are having this much problem with latency on your laptop (Unless you’re using the unmitigated disaster known as Windows Vista of course) as my Win 7 machine with its on-board chipset can easily achieve 7ms using ASIO4All, so latency using a quality interface and driver is pretty much a non-entity.

Just make sure you have the latest driver and ASIO drivers for your interface, as this can make a big difference.

Hope this helps

Bill
