Duo X as USB Audio input and MIDI device | EXPERIMENTAL

okay gave this a try:
seeing all midi in/outs and a pair of modx outputs, nice!
but could not get any audio out via macos default audio and also not in ableton

on mac its also grayed out somehow:

audio:


midi:

btw for the geeks: never seen that kind of top version, must be the latest source^^ :wink:

Will it be possible in the future to do this on the Mod Duo ? Or on a “hardware-upgraded” Mod Duo ?

It is technically possible, but requires quite more work than the Duo X.
In my opinion the work needed for it is just in the border of being worth it. We are too busy right now with other things.

What are the blockers that may hinder moving both the Duo and the Duo X to using the mainline kernel ?

On the Duo X side, yes, as the company that makes the SoC does not support mainline.
It is a community effort to get their patches in there. I have been keeping track of it, 5.2 had quite a few things merged, even more coming in 5.3
Things are a bit easier for the Duo, but the flash storage makes things quite tricky… something to evaluate at a later time.

by the way, the RT kernel patchset might be making its way to mainline kernel very soon :slight_smile:

Hello, I’d like to know the status of this. I have a Duo X and run ‘not windows’ so I’ll just give it a shot BUT are you still working on this? The idea of attaching an iPad to the Duo with MIDI and Audio access is tantalizing.

it is not working at the moment. mostly it is not a focus for us now, until there are other features out of the way first anyway.

but we are working a bit on it behind the scenes, resolving the case for Windows.

Thank you for the update.
Would really love that “reverse” USB MIDI!

hi, i did the ssh command but now the mod duo dosnt recognize via windows, i know u mentiond it before. i wanted to try the midi stuff because i want to use the modduo with my mpc one over usb- midi.

anyway. i tried to restore the firmware but the ssh command is still there. i cant connect via ssh to go back.

windows dos not find a driver for usb ethernet/rndis gadget (code10) i also tried the driver on wiki,.

what should i do now :wink:
thanks

edit: usb midi mod duox <–> mpc one works now. so in that case i can use the bluetooth connection for the gui, or are they other ways to get both working on windows?

you need to get some SSH again in order to revert this (some linux VM should do it). worst case install a factory reset image from https://wiki.moddevices.com/wiki/Factory_Reset_Images

thanks for fast reply. if i disable the usb-multi-gadget mode, midi in out via usb port is also disabled?
i dont need the midi host, just a midi port to use the mod duo as an instrument over usb.

thanks

edit: i did a hard rest like u mentioned, no usb midi :wink:

just be patient on this because it is a feature promised for the dwarf. so once we get to it, we will try to make it work on the other devices too.

if all you need is to send MIDI from the PC, consider a small USB-DIN-MIDI converter cable for now.

yes sir, i just use the DIN cable for now, i wanted to get all the gear with usb midi but its not that important for me :smiley: thanks for help

I was wondering about this, if there’s no hardware reason etc why it couldn’t work on the Duo X and people will be trying to make it happen then I will probably buy a Duo X and keep my fingers X’d

I tried on my Duo X, and I can’t access to the web manager, so obviously I didn’t bother checking if it works or not… Removed the file, rebooted and everything back to normal.

Is this happening to everybody? I’m with the latest software.

The “curious” thing is that I can access the DuoX vía SSH without any issue (with IP or modduox.local) and in the web manager says “connection refused”. Maybe this info is helpful for the “techie guys”…

the audio usb stuff changed in 1.10 already, so there is no point checking this here now.

When is expected 1.10 to be released (more or less)?

RC in a few days, maximum a few weeks. We need it ready for the dwarf, so we aligning its release with the beta batch that will go out very soon.
