RDUSB012AMidi
RDUSB012AMidi is a MIDI driver component for macOS CoreMIDI that enables communication between the system and Roland audio equipment connected via USB. It is a system-level MIDI interface rather than a standalone application — it works invisibly within macOS to route MIDI data from Roland hardware devices (such as keyboards, synthesizers, drum machines, and control surfaces) to any MIDI-capable DAW or application running on the Mac. The driver is installed and maintained by Roland as part of their hardware support ecosystem.
AI Recommendation
1 suggestionThis is a system MIDI driver component, not a standalone app, and it is managed through macOS CoreMIDI rather than through the App Store or a generic download. To ensure you have the latest native Apple Silicon build of this driver, visit Roland's support site and download their latest driver package or updater tool for your specific Roland hardware model. Roland has been shipping native drivers for their USB MIDI interfaces since late 2020, so updating to the latest version from their support portal will deliver a native arm64 build. If you are unsure which driver version you need, identify your Roland device model (typically printed on the hardware or found in its documentation) and search Roland's support pages for that model's driver download. Once you have installed the latest driver package, restart your Mac and the updated native MIDI driver will be loaded by CoreMIDI automatically. This step is important because Apple will remove Rosetta 2 in macOS 28 (September 2028), so an Intel-only MIDI driver will stop functioning on that release.
