hdjsMIDI.plugin
hdjsMIDI.plugin is a CoreMIDI driver for Hercules DJ control devices, specifically the DJControl MP3 hardware controller. It bridges the physical MIDI keyboard, pads, knobs and buttons on the Hercules DJControl MP3 to macOS, making the device visible and controllable by DAWs, DJ software and other MIDI applications. Like all CoreMIDI drivers, this plugin is installed as a system extension rather than a standalone application.
AI Recommendation
1 suggestionThis is a system MIDI driver installed by Hercules for the DJControl MP3 hardware. It is not updated separately from the host — you update it by installing or reinstalling the Hercules DJControl MP3 driver software from Hercules' official support site. Visit Hercules' website, locate the DJControl MP3 product support page, download the latest macOS driver package, and run the installer. The installer will place the CoreMIDI driver in the correct system location and make it available to all MIDI-aware applications on your Mac. If you no longer have this hardware, you can safely uninstall the driver by removing the plugin file at /Library/Audio/MIDI Drivers/hdjsMIDI.plugin, but be aware that your DJControl MP3 will not be recognised by MIDI applications until you reinstall the driver. Check the Hercules support pages to confirm that a native Apple Silicon build of the driver is available — if it is not yet updated by Hercules, the Intel version will stop working when Apple removes Rosetta 2 in macOS 28 (September 2028).
