Wow, looks awesome. I've been playing around a bit with m8c on Mac and Windows, and now I'm waiting for my RG351V to arrive. I also ran into the Rust rM8 project quite recently, so it's nice to see someone building upon that.
thanks a million David. just got rm8 up and running on my deck. I kept asking questions on here, figuring it out, deleting my comment, getting stuck again, another question etc. apologies if you got a bunch of notifications 😂 thanks again, awesome work
Hey thanks for this tut and for adding to the RM8 project. I’ve been running M8 headless on my Windows PC through Touch Designer, and I’m liking it so far. I just ordered an RG353M. Gonna try this out when it arrives. I’m hoping RM8 will work on the 353M, since it works great on the 353P. 🤞
@@MetroGradeGoods Hey. I haven’t had the best luck installing Linux builds on my RG353m. Some 353M’s don’t seem to load JELOS or ArkOS. It’s an issue with the device. Hopefully, you don’t run into this issue. Let me know if you have any issues. Also there are Discords that the JELOS and ArkOS developers frequent that have been very helpful to me.
I installed it on a R353V and it takes a bit longer than here to load. Also when I try to edit the configuration it crashes. I’m using Jelos too. I tried installing your recommend link from Lamaa but that one doesn’t work. Any tips? I have the real M8 but honestly the R353V looks much more nicer. Better display and stuff.
Hey that's awesome. I'd really love to make this work on my Powkiddy RGB30 that's also running JELOS. I don't really know what I'm doing and I saw the repo no longer accepts issues. Do you have an idea where I could go to ask for help if I get stuck?
hey again, i got a headless m8 and having so much fun. i got a problem tho, i bought an anbrenic rg35xx, wich doesnt support JELOS(i thought it was made for every anbernic handheld). do you think the rm8 client will work on GarlicOS too (an os for the rg35xx)? it would be a shame to have to buy a second anbernic to make one of these
it should work fine on just about any linux distro (not sure if GarlicOS is linux, seems like it's possible it's something else.) ArkOS is also nice on these devices.
Is there room in any of these devices to mount the teensy internally, so you don't have to worry about it flapping about when you're making music on the train/plane/etc ?
I don't think so, without a lot of work. It needs SDL and you can have to be able to compile rust for target. I think it also would have trouble with audio & input on switch, without some very custom code for that.
Great video and great project! Do you think it would work on a ANBERNIC RG35XX? For what I know it's a bit lower specs that the one you're showing off, but it also runs Linux with garlicOS.
@@DavidKonsumer thank you for your reply! I don't know what sdl is but I know it accepts ports like doom and Diablo 1 and also has USB C OTG, so maybe it works. I'll try as soon as mine arrives.

This is really cool, thanks for sharing. So, I got mine running, showing up on the screen of the device, but no inputs are recognized. Did you ever get something similar?
I wonder if I can get this to work with my Xbox series s? Wanting to build one before I buy regular M8. I mess with every kinda synth on the planet. But always feared trackers. Intrigued by them though.
hi I've seen the various links but I can't understand where I can buy this card with the cable to attach to the Gamepad It's not like you could give me a tip on what this device is called. Concrete works are increasingly respected and since it came out I've been dreaming of the M8. and I can't wait to install it on this device would you be so kind as to tell me what is the name of the cable with attached electronics to transform a Gamepad into an M8 I've been dreaming about it for too long thanks thank you guys so much and try to study these tricks!!!!
m8 headless opened nicely via chrome but then i realized that my m8 headless teensy is absolutely empty of and samples ,synths, or demo tracks ,so it’s kind of pointless with out any sounds in it . Maybe i loaded m8 headless improperly to the teensy or something. it responds to keyboard commands fine though so it seems like i set it up correctly Did your version of m8 headless come with sounds in it already ? thanks
Question... Do you have to keep the USB cable plugged in to run the headless M8 teensy, or is this just a way to install it to the root of your anbernic device and unplug it once its installed to Jellos/Linux!?
@@DavidKonsumer Oh… okay 👍 Yeah that’s what I was wondering… I thought it was Linux based. 🤔 (So the anbernic just functions ONLY as a screen and the buttons are used for navigating around?)

if you want to put samples on the SD-card, do you have to pull the card out of the teensy and put it into an SD-card reader ? or does the teensy-headless-setup also work as an "SD-card reader" ? because I cannot find any folder if I attach the teensy to my laptop, thanks
hey! followed the full tutorial with a 351v with as the video said is pretty much the same but when i hit the port m8 option screen goes back and never loads the m8 , do i have to do anything else like habilitating the otg port or something like that? i really want this to work and cant do it
@@DavidKonsumer OK, thanks! Iam getting the ANBERNIC RG351V now. I am a bit scared about setting this up since I am a newby in that world. Not with Synths and hardware devices though...Anyways, wish me luck!
hello there, could you please tell me, do you think this build will work on the rg353m? if so, should i complete the github tutorial for the 353p or the 353v? (is in, the part on the tutorial in which it says to run the 'cp rm8-RG353_.json rm8.json' script)
yep, it should be. depends on OS, but JELOS and Ark work and runs on that. The only difference between different devices is mostly the joystick ID. See github.com/konsumer/rm8/issues/2 for details on how to set it up, if your joystick is not working with the config file, then the ID is unknown, but it's not really tied to the device, more like a specific joystick ID, so you can plug in a keyboard and make it work (following directions on that github issue)
Would this work on the Retroid Pocket 3? What are the requirements for it to run on a device? Does it just need to be capable of running JELOS? I don't think it works on the Miyoo since that doesn't support data transfer over USB.
The Retroid Pocket 3 is an Android based handheld. It won’t currently run JELOS, which is a Linux based firmware. I’ve heard skepticism in the community that the Pocket 3 and Pocket 3 + will ever run Linux well, just based on the compatibility of the chipset they both run. It seems like these Anbernic devices or a SteamDeck would be a better choice to run rm8. (That said, apparently there is a version of M8C that can run on Android, so who knows, it might be possible.)

I also can't find all the help people refer to on Discord, so I'm hoping for a video guide.
Hey, I can load the M8 on JELOS, but cannot do anything. I feel like this may have something to do with the fact that none of the JSON in the rm8-RG353P seems to correspond with the buttons of the device, it just references buttons on the keyboard (the file named rm8 has all of this in it of course). The text in this file is identical to that in the rm8-qwerty file, so I can't help but think this is a mistake? If not then maybe I've done something wrong, but the M8 is there, I just cannot control it at all, nor can I access the JELOS menu, all I can do is power it off or restart it. I searched a lot for examples of JSON button config so I could try to do it myself, but without knowing exactly what the device's buttons are called, there's no way of knowing how to sort this out. Please help, as I'm very close to having this working and would love to use it. Thanks

ArkOS is ok. It's pretty much the same as an old copy of JelOS with some nice mods. You can also just use an old copy of JelOS, it's still available.

Basically, each device shows up as a new ID, so we have to create a config file for that. Also, often you can just rename another file, and insert the correct ID, and it will have the controls set well enough to configure it further, which requires editing in a text-editor, but might be simpler if you don't have a hub handy. I think the core thing is it's not really specific to any distro or anything, it's just a problem with how the joystick stuff works.

It needs SDL, so if you can run that (very common, on Linux, Mac, Windows, etc) it should basically run. That said, I don't think onion is a full os (not totally sure, no device to test with) so it may not have SDL.
