yeah it’s been an interesting past eleven months, as far as working on music goes. my issue has been that my wife and I are both working from home and are generally around the house most of the time. I used to mainly write music while home alone, primarily so I don’t feel self-conscious about possibly annoying the hell out of her (though she never complains about it) with the same four bar loop for hours on end. but… I’ve had to overcome that; accept that it’s OK to have others hear you working, and just turn the volume down. but until I got there, I did a lot of short/quick writing that would always end up in something I’d revisit days later, wouldn’t have interest in taking further, and erasing it entirely. basically most of the last year was this way. lots of lost ideas… now it’s freeing not to feel “forced” to work on music just because “oh wow I have the house to myself for a bit, I HAVE to work on music now!”
it sounds like some people (and the OP) don’t have a space where they can leave things set up and just turn it on and go. that’s huge. I’d say try and do this first, even if it means using less (or different) gear in a small corner of your place, working with headphones, etc…
I agree with @LaughingAnimal that getting new gear does help inspire ideas. that doesn’t have to mean MORE gear though. do a long-term trade with a friend, or someone on here. even if it’s just a guitar pedal, new stuff to change things up can spark ideas.
it’s also helpful to have “maintenance days” to not really work on music but work with your gear still. days where you don’t feel creative, necessarily. maybe that means a re-organizing process you’ve been putting off. or changing your setup to something that could improve your workflow or allow ideas that were previously difficult or unlikely to be explored. or even just write patches on a synth, store 'em and move on. come up with something crazy on a modular, to be sampled and explored later. re-organize your OT sample collection. download and sort through some new samples. update and explore a new OS on a machine, etc… lots of times I feel these “off days” inspire totally new ideas out of nowhere.
