Makes the MIDI device corresponding to the Work fast with our official CLI. The API enables the developer to enumerate input and output interfaces, and send and receive MIDI messages, but (similar to the aforementioned APIs) it does not attempt to semantically define or interpret MIDI messages beyond what is necessary to robustly support current devices.
