Buncha 80s and 90s digital rack gear and other stuff I scooped in the late 2000s when I worked at a record shop and thrift shop at the same time and it was nearly free (seriously there was a period in time in the mid 2000s when a band I shared a space with had three Juno 60s piled up on the floor in the corner because they were just cheap keyboards nobody else wanted, so they used one until it had a problem and then put it in the corner and bought another for $150-$200 because it was cheaper than repairing them; they had some SH-101s too, same deal; the moral is never throw away anything if you can avoid it), and the early 2010s when I was earning more money for a year and a half than I did before or since and people cared about it a lot less than they do now. Sometimes a homemade electric guitar and amp. A handful of fancy things like an Octatrack I've been able to pick up over the last 5 or 6 years when freelance work is good. Try to build stuff from kits or scratch as much as possible these days (or find things that are free or cheap broken and try to fix them), even if it isn't cheaper in the end it lets me spread out the cost so I can manage things I couldn't even think about buying in one go, like for example I've been collecting the parts to build a Kijimi since last April and should be able to start working on it in a month or so. Hopefully it will work and show up in some tracks this spring.
Record and mix in Reaper with mostly Airwindows plugins and hardware reverb (for commercial stuff it's mainly Valhalla, TDR and Klanghelm standards but MJUC and the TDR EQs are the only ones I use in nearly every mix anymore).
I really respect the people who do everything ITB, I've tried a lot over the years and I never like the ideas I come up with that way.
