Hello,
I recently purchased Blackhole and attempted to install both the regular 64bit vst version with nks support, and the vst3 version. Both versions seemed to install as expected to the indicated folders – however, the vst3 version refuses to be detected by Ableton live. I’m pretty convinced at this point that there is an issue with the vst3 version of your blackhole installer, considering all my other vst3 plugins load without issue.
Any advice would be appreciated – thanks!
