Ok, I am almost there, though I still need some help.
I loaded ASIO4ALL, figured out how to use it and am running it now.
There now seems to be no need for JBridge, and latency for vocals and instruments seems fine, and no crashes so far, fingers crossed.
Sounds are clear. Miroslav instruments were all found instantly and loaded up without a problem by SampleTank 2.5, which is priced just about right for me.
I just have the problem where the patch randomly...like disappears, or almost totally loses its velocity! It's still there, very faint in the distance, barely registering on the meters. All the settings remain the same, the velocity is fine. It's like it is partially losing the patch, or something. It's ridiculous. If I call up SampleTank and double click on the patch, it is totally back to normal. Very hard to work this way.
