What devices are these? I’m playing the patch and it works as intended (including the clock output), but I’m just using USB-C MIDI, no other adapters in between the controller and the MetaModule.
In the Working MIDI devices thread, someone reported that the Digitone worked “but only with a specialised Din > usb3 cable.”. I don’t know if that’s a thing included with the Digitone or Digitone 2?
It might help in finding the issue to first simplify your setup as much as possible. We’ve had good results from cheap DIN5 to USB adapters like the “ESI MidiMate eX” reported in the above thread. I use this one when I need to USB MIDI Adaptor. These adaptors present themselves on the USB side as a MIDI device (not host), so that’s perfect for using with the MetaModule (which always is a MIDI Host).
Can you try going from the Digitone || through an adaptor like that one, and then directly to the MM with nothing else in line? You should be able to connect MIDI IN and MIDI OUT to the DIN->USB adapter, in case you also need to send MIDI back to the Digitone.
Another thing that can be simplified is to disconnect the AIO. If it’s faulty (or the cable between the MM and the AIO or some noise in the system, etc) then in the worst case the main MetaModule can fail to detect if a jack is plugged in or not. So removing the AIO from the system (disconnect it from the MM) will take one potential source of error out of the equation.
