The only issue with AUv3 hosts is I think it taxes the system rather more than just addressing the one program (like SWAM or Minimoog Model D).

One thing I found amazing was, because it’s monophonic (although the solo strings can double-stop), native latency is astonishingly low (under 6ms) for the saxes. Highly playable and zero glitches!

My needs for now are simple, I'm still trying to not run before I walk yet!
