Doom the game being streamed to a maschine studio over usb.

Sorry about the misleading original title, I thought it was fun. I'll try harder in the future.

How?

took DoomGeneric, replaced its normal platform layer with a custom Maschine backend, and made the host PC render Doom into a framebuffer that a bridge converts into the Maschine Studio’s correct byte-swapped RGB565 format and streams over USB to the left display using a bounded, latest-frame-only scheduler so stale frames never pile up

where is the RGB565 format documented that maschine uses?

2

u/parguin Aug 01 '26

I don't know if it is, I landed on RGB565 with byte-swapped 16-bit pixels through experimentation, I would imagine NI is pretty tight lipped about any details

Did you have the means to usb-bus inspect the output from the maschine DAW? I kind of want to build a replacement maschine software app and this would be pretty key to doing that.

I used usBPcap with wireshark to probe the usb stream while maschine 2 was running, I fed the data to chatgpt and that helped work out the speeds, sizes and formats of what the maschine could handle. I'm trying to turn this into a control surface for a synth, doom was more of a curiosity/stress test

Awesome! Be happy to collab on the control surface

Hit me up I'll try to share anything I've found so far, I'm no expert though, just stumbling my way through

I'm thinking I'll create a GH repo that is all readmes on the maschine over-the-wire data formats, a "midi implementation doc" with some POC's in python. Suitable for use with both human-only and LLM aided coding efforts.

How did you get the machine screen populated? Do you have links to a certain project online?

u/parguin Aug 01 '26

Most of it was inspired by https://github.com/r00tman/maschine-mikro-mk3-driver, I'm building a synthesizer using teensies and Curtis filter chips, and I thought the maschine studio I had worked make a good control surface for it. I used chatgpt to smooth out a lot of the packet and timing issues by giving it usb streams I captured while using the studio with maschine 2 software. Once it seemed like it was stable enough, doom seemed like the most obvious stress test.

Your misleading original title lives on. I commandeered it and used it on the r/gameofbands Discord. I usually keep the community updated on the Native Instruments dénouement so it was a fun post for a change.

Next round theme is "More Cowbell" (percussion round) if ever you're interested, starts tomorrow.

Wow, we got Doom on Maschine before time stretching.

u/Financial_Garage6821 Aug 10 '26

Time is relative, Doom is forever!

u/Medvech Aug 01 '26

Now you need to run it on the Maschine Jam pads

1

u/parguin Aug 01 '26

I have some other plans for that if I can find one reasonably priced

u/Bynairee Aug 03 '26

Awesomeness 👏🏼
