Hello
I’m trying to update the firmware on an RK-002 but can’t seem to do it … or to tell whether i have done it as I can’t make the cable work with my DT
The cable came formatted for Volca Sample. The RK-002/DUY site can’t find the cable when it’s plugged into my DT … do I need a midi hub to update the thing, or can I update it via the DT
Thanks in advance
What other midi devices do you have mate?
Took me about four hours of switching things around plugging in different items
Then I plugged it into my tb-03 and it was listed straight away
This was to update the firmware I must add
Do you have an audio interface with MIDI? The few that I’ve tried with the RK-002 worked no problem, I think they all provide the necessary juice.
Got an arturia minibrute 2s & a Roland mc101. My interface is a second gen Scarlett 2i4 which doesn’t do juice
I’ll try the Roland maybe
I recently had troubles with win10 and flashing it. Found an old laptop, installed linux on it, and used a steinberg ur242 to do this. Perhaps, maybe…
For flashing you need 2 midi ports. midi out: dark end, midi in: orange end
What browser are you using too? it has to allow or at least you have to allow communications
I’m using chrome and chose block 
so had to use incognito thereafter
dave mech who is on this forum and youtube has a really good vid to set it up
Thanks everyone – tried flashing it with the Roland 101 and that works. Now to try to understand how to use it (I’ll check out Dave Mech’s films…)
This worked. Thanks
I am trying to upload a self developed Sketch to the RK002 on my Mac M1. When I use Chrome to upload one of the online-sketches everything works fine. If I use the Java-Uploader, that is launched from Arduino, it ends with “cannot connect to cable”. When I disable the MIDI In, it “works” as in “software thinks it sends data and updates the progress bar” but when I read out the Cable in Chrome again, it shows the old firmware. So it seems, that MIDI in Java on my Mac M1 does not work correctly. I have not found any other way to upload my own Firmware to the cable, what makes it completely useless for me 
Its not my first custom firmware, and it worked like a blast before, but that was before I bought an M1…
You could try to install a linux in a vm and do it through that.
Virtualbox could work perhaps.
Yeah, if I don’t find any other solution, Ill try that, or try to upload it with a Raspberry Pi or something.
Does anyone know what programming language the scripts must be in for the RK-002?
I read through some of the scripts available on the Retrokits site, but didn’t see one for ‘fixed note length’, so I’m thinking I’m going to have to code it myself.
the official sdk is for c (arduino ide)
here is a starting point for your research: RK-002 MIDI Processing? Just DUY it! - Retrokits
Thats C/C++ in the Arduino-Environment.
We are currently testing a RK002 editor/compiler in the browser so you don’t need to install the whole IDE environment anymore. If people are interested send me a message and I’ll give you the link to test.
No saving from the browser to the online DUY DB yet but you can paste code to a text editor to save locally, it looks like this:

That looks fantastic!
I assume that only works with chrome, right?
If not (I have firefox), I’d like to test it.
You guys are awesome!
Great and thanks, I sent you a message 
Thank you!
thumbs up!
I did not want to mention it here (just gave a hint with “any other solution”), but @grit answered my E-Mail very very quick and sent me a link to that online tool, I tried it and it works great! Not saving is not that big of a deal, as the page does not reload from itself.
