The author of the excellent (at least IMHO) freeware Molot compressor has released a beta of the new plugin - Limiter №6. There are some testers already claiming that this will be their goto limiter. I haven't got better results than with FG-X in my brief limited testing, but it's more than likely due to lack of experience. It would be interesting to know what other users in this forum think though?
And btw, both plugins are available in Mac VST format as well although 32bit only.
