It can be, yeah. My first dive in set me back a lot of money when I didn’t really have it. I ended up selling it off to a friend about coming close to recouping, but I always missed the gear. I’ve slowly dipped a toe back in, but with a very pointed focus that lets me keep the cost and size down (ie generative/sound gen - no traditional sequencers or drums or anything that a ‘standard’ setup would have as I can do that all ITB).
To be fair, a lot of the same functionality can be found in something like Reaktor, M4L, Grid or other soft-modular environments and I do a lot with them, but they’re also more finicky, labor intensive to set up and unless you have a head for the underlying tech, bound by what other people develop. It’s also less tactile and immediate for me and I don’t get the same knob-twisty exploration joy that I do from hardware.
Since I’ve come back to modular, I’ve really been pushing the DIY aspect as it dovetails with my enjoyment of electronics and tinkering and building things. It’s sort of another hobby unto itself, but I’ve found it really rewarding to make sounds with a thing you built and customized. It’s also a shitload cheaper.
