Personally, it always comes down to lowering the track volumes on the Rytm to around 90 or so to start with and then I have a little bit of headroom where I can bump up volume a little if I need to for a certain track or two. Then I set the Tempest’s volume pretty high (just over 3/4, I’d say) and I almost never use the Tempest’s distortion or compressor. With things set up in this way, I’ve gotten decent results.
I’m also curious to see if anyone else has input on this.
