I would recommend either FL Studio or Ableton. As Logic Pro X is only Mac, and I have no experience with it, I cannot say. I personally would recommend FL Studio, as it’s what I use, but many prefer Ableton. Neither are designed like Auxy, but the workflow adjustment is easier on FL according to some people I’ve talked to about similar things. As I myself use FL alongside Auxy for things such as mastering, the adjustment wasn’t that difficult. It just takes a little getting used to.
Especially for soft synths, I would highly encourage Serum, as it’s practically a beefed up version of the Auxy sound engine. This has been confirmed by the devs, who based its design off of how Serum handles its sounds. It’s quite a fantastic program and is easy to pick up but is so deep it’s worthwhile mastering it.
Workflow is still rough, and I’d also highly encourage you to look into exporting stems from Auxy and importing them into a DAW such as FL or Ableton. This is how I produce my music, and it works wonders. I’m probably going to do some sort of tutorial in the future about how to interweave the two, because it’s not that difficult once you really start to see outside the box.
