Also, I notice there are only three rea… plugins shown when i search (see above), but many more that look like they probably ought to be:
This seems to relate to the problem @Wilx had (Cantabile can’t see reafir-standalone any more.), where the FIR plugin he used was no longer showing up, He concluded that it was specific to Windows 7, which I’m still using, and that Cantabile didn’t have that problem in Windows 10.
So, it seems there may not be a solution for my current setup. I do have a couple of PCs with Win10 on but it annoys me so much I can barely stand to do more than watch YouTube on it. At some point, I may try running Cantabile in WINE or similar, to see how that goes. For now, I’ll just settle for what it still does
