Display MoreRecord in analogue instead of via spdif.
Then Kemper clocking is a non-issue.
Record everything, not just guitars with ample headroom and at 32bit float if you can.
Use the highest sample rate practical.
I do almost everything at 96k.
Monitor with as good a rough balance as you can. Some people call this ‘always be mixing’; but it’s important to have perspective on context as you overdub; don’t just throw stuff on and hope to sort it later.
It’s far better to commit to a sound and make your subsequent choices BASED on those you’ve already made. Otherwise you can endlessly chase your tail.
“Perfection” is both unattainable by humans and highly overrated. Don’t “fix” everything. PERFORM.
I also prefer the simplicity of recording in analogue and I'm very much a fan of always be mixing. When I'm tracking I don't want to have the green screen experience, where I have to imagine what it will be fitting into. That's why I use EZ Drummer for songwriting, because I simply can't find the groove with just a click track.
So, I like to get a solid mix going so that when I'm tracking, it feels like I'm playing the song rather than adding another widget. As you mentioned, it's all about the performance, so anything I can do to keep myself in the moment makes for a better end result.
