Based on what you wrote, maybe the problem resides in the SWAM instrument itelf. SaviHost doesn't even need ASIO to work. It will work with Windows Audio (although with more latency - but in Windows 10 you can even reduce that). So, if it cannot open SWAM, and neither can Cantabile, something wrong must be happening with SWAM.tmoody wrote: ↑Thu Jan 31, 2019 12:18 am @fmr -- Yes, I did place the Savihost executable in the same directory as the .dll file that I wanted to load, and I did rename the executable to be the same as the .dll name, minus the extension. I used copy/paste to do this, to avoid typos. It didn't work. Savihost would open in that directory and show me a dialog box with the .dll in it, but I'd have to double-click that file to get Savihost to open it. And this worked, for a while.
Then, for no reason that I could identify, Savihost would force close after trying to open that .dll file. Then I tried Cantabile Lite, which would load the SWAM plugin into its display, but as soon as I clicked to activate it exactly the same thing would happen. So the fault is either the SWAM engine or ASIO, I guess. Savihost and Cantabile Lite can't make one or the other do something, so it closes. So if the fault is with ASIO4ALL, a replacement should help. If it's with the SWAM engine, well I don't know.
I never tried those plug-ins so, I cannot say how they behave. But I second the suggestion for you to install REAPER and try it. REAPER is a very stable and forgiving (in the meaning of compatibility) host. If you experience a problem with REAPER too, then the problem must definitely reside on the SWAM side, be it either connected to your particular system configuration or the SWAM instrument itself.
