QA:Testcase PipeWire Jack Midi Routing

JACK MIDI Routing

This test case tests that PipeWire can support JACK applications with MIDI routing.

Setup

1. This test case should be performed on bare-metal machines. In case you want to test it on virtual machines, consider the USB device pass-through for required devices.
2. The computer must be equipped with a sound device.
3. Install a desktop version of Fedora 34 (or later).
4. Install the pipewire-jack-audio-connection-kit package using the dnf install pipewire-jack-audio-connection-kit command. Sometimes, the --allowerasing option might be necessary for successful installation.
5. Install the yoshimi and qjackctl packages.
6. Connect a USB MIDI keyboard to your computer.
7. Connect your speakers (headphones) to the default sound device.
8. Perform the following steps as a regular user.

How to test

1. Start Yoshimi yoshimi and check that it starts.
2. Start QJackCtl qjackctl and check that it starts.
3. Go to QJackCtl and click on the Graph button to open Jack connections.
4. Find yoshimi in the graph and make sure that its output (right side of the icon) is connected to the system’s playback slots.
5. If not, create a connection to send Yoshimi’s output to the system playback device.
6. Also, create a connection between your MIDI keyboard MIDI output and Yoshimi’s MIDI input.
7. Play some tones on the MIDI keyboard and confirm that the sound can be heard over the connected sound device.

Expected results

1. QJackCtl and Yoshimi start successfully.
2. The Graph tab of QJackCtl shows devices and allows to connect them including the MIDI connections.
3. Yoshimi produces audible sounds which means that all connections work properly.
