My current rig is:

Arturia Microfreak - Basically my dream synth. I did take the keybed off though, was sequencing it externally and i needed the extra desk space.
Korg Electribe ER-1 - A great drum machine, really snappy. Mine has a sentient (broken) pan encoder, but since use the mono jack on my mixer for it there's no issue.
Korg Monologue - A mighty monosynth capable of sinister acid tones or lovely leads. I also like making weird bleepy drum noises on it, though I prefer to do those on the ER-1. Making formants with the filter is also really nice.
MAM MB33 Retro - ReBirth on iPad was my proper introduction to electronic music, and so I've always been a fierce follower of the acid house sound. I had a Roland TB-3 for a long time, but I sold it and replaced it with this much smaller unit. It's not spot on to the OG 303 (especially not the square wave!) but I reckon it sounds very exciting and appropriately liquidy for all my 90s rave needs.
Modal Skulpt - An impulse buy that turned out very well. Has a lovely warm sound for a digital synth, brilliant filter and a 'spread' function that makes the unit sound huge.
Novation Circuit - the brains of my rig. I love the sequencer on this thing so much I bought another one to sequence the rest of my gear. I use the two units as an eight track drum machine too, loaded with samples from ReBirth for maximum nostalgia.
Roland VP-03 - Everyone needs a vocoder at some point, and this is mine. It's a bit finnicky to use, but I love the sound on it. Works great as a microphone when I'm playing Fortnite with my mates too, so that's a plus I guess.
Casio HT-3000 - Bought from a Cash Converters a while ago, lovely sounding 80s keyboard. Mine is basically a preset machine cos the internal battery is toast, but fortunately those presets are the business.

There's also my Korg Volca Sample, but that's getting replaced on Monday by an Elektron box - the buttons have deteriorated on it and they don't work much now (probably cos I used to make entire tracks on that thing - oops!) I've got other synths and gadgets like Pocket Operators and Volcas, but I don't really use them enough to count them as part of 'the rig' per se.

All my jams are recorded live into a Alto ZMX122FX mixer, which is run into a Presonus Audiobox iTwo, then into Audacity so I can check levels and export the thing. EQing and FX are done either on the synths or the mixer rather than computer, cos EQing every synth at once doesn't seem like a good idea. I've just started recording with Windows 10 after using MacOS my entire life, and it's surprisingly less painful than I expected.
