I decided to stop waiting on the master compressor, as I don't want to put hopes into anything that hasn't been advertised as coming.
Used RNCs are $100-$140. I got a handy little HPF sidechain cable for mine, which makes the RNC totally usable for bass music. RNC will live on my forthcoming Digitakt's outputs, and I plan to (re)sample through it as well.
Re: bugs, I'm hopeful that by the time my DT arrives (maybe a few weeks?), the biggest ones will be smushed.
