I love Axoloti for this purpose, and there’s even Akso now, a smaller more powerful version of it. The only problem is I never quite settle on what I want my axoloti to be. Sometimes it’s a looper, sometimes it’s an fm synth or sequencer. So i’ve never settled on a proper enclosure.
This is some fantastic inspiration of what can be achieved with Axoloti
Norns/Norns shield (while screened) make for excellent self contained music boxes. I have a Fates, but have been strongly considering getting another so one can function as sequencer/synth and the other looper/fx.
I don’t have experience with it but I love the idea of the gecho loop synth. I’m not sure why I keep putting off grabbing one. Tons of features, and the hardware is so beautifully considered, the designer truly cares about the design of this instrument.

btw love the sound of your music! To fit your style, which is ambient/cinematic I feel like Plinky could be a good fit. I’ve also been intrigued by the Elmyra which is a kind of low cost alternative to the Lyra-8
Tbh some of the most fun I’ve had in recent weeks is with a looper and my Korg Volca FM. Especially with some custom patches from Dexed, you can spend hours playing around. Sound wonderful with a couple of fx pedals.
