Only one of a pair of MIDI devices are listed

Describe your issue here:

I have two Helix Rack devices connected, yet Ableset only shows one of the devices.

Both devices are controllable by the HX Edit software and vice versa. Device manager also shows both devices are connected.

This is how Ableton lists the two Helix devices.

Please fill out these values to make it easier to troubleshoot:

  • OS and Version: Windows 11 Pro
  • Version of AbleSet: 3.0.5
  • Version of Ableton Live: 12.3.2

Should both Helix Rack devices be visible in the MIDI Mapping page?

Hey @Michael,

Please excuse my super late reply to this topic!

It seems like this is an issue with how the framework I use to build AbleSet handles MIDI ports. If two ports share the same name, it only shows up once in the APIs I’m using to access MIDI devices for MIDI mapping.

Unfortunately, there’s not much I can do from my end to fix this. If there’s any way to give your devices a different name each, that might be a good workaround.

I’m sorry I can’t offer more help at this time :confused:

Thank you for the reply. Are you able to share the product you use to enumerate the devices? I would like to see if they have a suggestion for how I can update the names.

Either way, I can revert back to using MIDI via DIN cable and a U6MIDI pro device rather than USB.

Thanks again!

Sure! AbleSet is built with Electron and uses the Web MIDI APIs for enumerating and accessing MIDI ports. Using DIN cables with a MIDI interface sounds like a good workaround :slight_smile:
