If you'd disconnected it and dried it immediately you may have been fine, sorry to say but smell of burning = short somewhere which has fried some part(s) of the circuitry,
Might be salvageable if you can find an electronics technician locally. But really, modern electronics are not designed to be repaired, they're designed to have the burnt-out boards removed, recycled, and new boards installed. Repairing electronics mainly became a thing of the past when surface-mount components became a thing with everything assembled by robots not humans.
If you can't find a local electronics engineer who will look at it for you, I think your only other option is to reach out to Arturia to see if there is somewhere you could send it for repair.
Alternatively if you have house-contents insurance in your territory you could see if you can claim through that, it usually covers accidental damage, though you will doubtless have an excess to pay, just like car insurance.
