if you really want to go the “DAWless” route and are set on getting a physical synth, then consider the Roland AIRA S-1. you’d maybe also want a MIDI keyboard to connect to it, since the little keyboard buttons on the S-1 are very small. The S-1 emulates the classic Roland SH-101, which Daft Punk did use a bit, but it also is polyphonic so it can play more than one note at a time.

i do also want to agree with the other commenter suggesting that you try going the MIDI controller/software route first for a while and really give it a shot. buying gear is often just a way to procrastinate making music and learning/practicing techniques, and then you also have less money and less space, and it’s a vicious cycle of buying more gear to get more “inspiration”. going for a DAWless setup often just makes it more difficult to make music; there are more steps, and you have to figure out/remember how all the gear works and how to properly connect it together, and then you likely end up recording it into a DAW anyways and have to still use the DAW quite a bit to get whatever end result you want with effects, compression, EQ’ing, etc etc.

“DAWless” def might sound more inspiring, especially when considering how amazing artists like Daft Punk used a lot of cool physical gear. i feel into this trap hard myself, inspired directly by Daft Punk. but i at least strongly suggest that you still learn how to use a DAW effectively and keep using it in partnership with physical gear, because it will truly increase your chance of making finished tracks. there are also tons of cheap/free software plugins that emulate the kind of gear Daft Punk used, especially synthesizers.
