Wanted to see if anyone is using the PreSonus Firestudo Project.
I just picked one up and seem to be running out of system resources when using Vegas 4.0e.
If it's new, take it back and swap it for something like RME. The Firestudio was a bad device (not all Presonus is, just particularly the FireStudio). Their support for it is cack too.
[I know that does not help you otherwise, but it might do in the long run]
I have a Firestudio/Digimax FS setup that works fine. So "was a bad device" doesn't really make much sense to me. It works fine and as long as you can get a handle on buffer settings in Vegas, you should be good to go.
It's not so much that I was having "issues", it's just that Samplitude and REAPER (especially) have way better user features for tweaking buffer/latency settings. It's just laid out kind of bland without much user tweakability.
