gotta figure out what works for you. It took me a ton of time and gear investment to get to a point where I was like... ok this setup works for me.
What I do:
Control plane= octatrack. I use the octatrack to define the flow of the song, although I usually manually change patterns instead of the arranger. Create patterns copy, make variations, add new sections, lot of copy and paste. I sequence a few synth things with midi. So I'm basically getting drum machine, sampling, etc. for free from this one box on top of being the master sequencer. It's my daw equivalent.
As sort of an extension of the octatrack, I have the Analog Four, I sync this so that it changes patterns at the exact same time. I sequence CV on my MS-20 with this, as well as use the 4 tracks to fill in and add little bits of acid, leads, noisy bits, etc.
I don't have a very amazing mixer(A&H zed 14), but it's damn solid for the price. I send one set of stereo to a reverb that I use as a send for everything at various levels, tweak it live to add a verb tail to various bits. I also have a OTO BAUM on the main insert bus to add a bit of glue to the mix, but I usually do less of that now so I can better master it in ozone when I'm putting a project together. The other 2 aux I use for what I can, I usually send it back into the octatrack for fx processing, sampling from things on my mixer, or for "bouncing" down parts. Mixing can be very frustrating without more sends and channels, so you have to get creative with limitations and just live with the results sometimes. Sometimes I bounce down and eq things on the octatrack, add reverb, screw and chop to help "mix" things different.
So then basically after that, just keep practicing/recording stereo takes on a zoom digital recorder until I get it right. It's harder to switch projects without a computer (I miss being able to do this), but I do get to listen... have a sleep/think about a track I'm working on, come up with ideas, listen to recordings on different setups and think about what I'll tweak. Eventually I'm just like, ok it's never going to be perfect, go on to the next thing, I may or may not hate it later but not every song can be a success. Gotta make shitty songs to progress sometimes.
