This should be easy, but it’s not turning out that way. I’m trying to delete several convolution filters I no longer use. I’ve cleared them, removed the filter, and even moved the source wav. files to the trash. They disappear momentarily, but not permanently. The next time I open the DSP engine they’re back!
Yeah, that’s exactly what I’ve done. Several times. The following screenshots show what I’ve started with, what it looks like after I follow what you’ve suggested above, and what it looks like after I close and reopen Roon, or even just switch to a different convolution filter. Weird. A bug?
