This manual test suite verifies that Web MIDI MidiAccess objects are only allowed to send and receive messages permitted by the access level they are constructed with, independent of the site permssion allowed.
Step 1: Create a MIDI access object with or without SysEx access. This may require accepting a permission prompt.

Step 2: Send each type of MIDI message and check the results. This will send messages to all connected MIDI devices and ports. There should be at least one loopback input and output, such that the output will send to the input. This may need to be set up in a system-dependent way before running the tests.

Step 3: Repeat Step 1 and Step 2 with the other type of MIDI access object.
