Posted about this issue here:
I’ve got the same issue of needing dspMixFx and and not wanting any of the bloatware that comes with it. But, I see no way of simply downloading dspMixFx alone without all the other junk that interferes with my system periodically. I’m also using Logic Pro X.
Funny, thing - I was using Cubase (free version that came with my UR44) - but one day they changed/updated Cubase preventing me from installing - actually it was severely crashing during installation. I got so fed up spending hours on the internet trying solve this problem that I ended up buying Logic Pro X. Problem solved. Two clicks later and Logic Pro X was up and running without any fuss whatsoever - as it should be. The crashing issue of Cubase was a total joke.
So, now I need to solve the issue with dspMixFx - but have a feeling I’ll just ditch the Steinberg UR44 audio interface for something more compatible with Mac/Logic. Which kind of sucks because I really like the UR44 on its own - just not their bundled software and this eLicenser crap that mucks everything up.
Sorry I couldn’t offer any help though.
Actually, now that I think about it - you might try deleting the files that I deleted - see my other post using the link above.
