Imposcar 3 was working in KK up until I decided to test it in Ableton Live where I confirmed the same issue we have had for years, the GUI does not show!
While that was not unexpected, I now launch STANDALONE KK and what do I find, the GUI is now not even displaying there for EITHER VST2 or VST3 versions.
I have also reinstalled Imposcar, reinstalled KK, deleted all appdata files, rescanned and nothing works, it is fried now.
I expect no actual resolution, just pointing out yet again how terrible this software has become and what kind of experience users can expect if you decide to invest into this world, a miserable and unreliable one…
