This is normal. The Organelle M’s TRS-MIDI ports are always ‘on,’ but devices connected to these ports are not listed in the Organelle M’s MIDI page. Only connected USB-MIDI devices are given names on the Organelle M’s MIDI page.
Are you using a TRS-MIDI Type A cable with the Organelle M and your MIDI Controller set to the same MIDI channel? (Also, did you power your MIDI Controller with an external power supply?)
Sometimes USB-MIDI controllers are said to not require a driver (aka ‘class-compliant’) but the manufacturer really means that the controller has only been designed/tested to work via USB with Windows, Mac, and/or iOS. This means that a controller may or may not work with a Linux OS like the one that runs on the Organelle. This is frustrating for everyone.
Looking at the Minimum System Requirements (under ‘Specs’) on this M-Audio page, it only lists the following operating systems:
- Windows 7
- macOS 10.11
…so it doesn’t look like your MIDI controller supports USB-MIDI with Linux OSes. It might be worth reaching out to M-Audio about this to confirm.
