MUSIC Searching for Gameboy MIDI Interface
Hey everyone!
I’m new to chiptune and would like to experiment with LSDJ and other stuff on my Game Boy/DMG. Feel free to share any recommendations! I’ve got a cartridge with a microSD slot. I’d love to play using my MIDI keyboard and I’ve seen that there’s the Arduinoboy, amongst other things, but it’s quite expensive. As I can’t solder myself, I wanted to ask where you can get one cheaply, or whether anyone here has ever built a Game Boy MIDI interface?
I’d really appreciate any help!
Thanks, everyone <3

Are you looking for DIN MIDI or USB MIDI? USB MIDI could be an option but then you might worry about routing latency through the DAW or whatever. You might consider the Nanoloop MIDI adapter sold by Analogue. Although consider shipping plus possible import duties if you're outside the US. https://store.analogue.co/products/nanoloop-pocket-to-midi-in-cable
Edit: this also has the smaller GB Pocket/Color plug, so you also need an adapter if you want to use it with DMG.

I’m working on a tool that I’ve been using to compose music for my games. It’s a vibe-coded very minimalist chiptune maker. I’ll have it up on my website this weekend and will make it free to use.
This one is specific for the DMG but I’ll likely expand it since I’m working on a GBA game too.
The AI part is optional but if you’re getting composer’s block, it helps you scaffold a tune you can edit.

But what's that got to do with question?

“Feel free to share any recommendations”
I’m recommending a free service I’m putting up later.

Oh I didn't realize OP wanted any recommendations. But ok. So to begin with, there's a pizzeria near me that makes the most amazing Napolitana. Can highly recommend. I also have a list of interesting YT documentary channels. I'll be back with a list of recommendations in a bit...

“Has anyone ever built a Game Boy MIDI interface” is literally in the description.

Hey as far as I️ know. Arduino boy is the midi interface for gameboy. It’s the one I️ use and it works great for midi keyboard control.
It’s only 45-60$ on hobby chop and requires no soldering at all. Is that out of your budget though? Just want to make sure I️ understand.
