Ubuntu – How does one set up a MIDI keyboard


I would like to set up my keyboard via my midi-sport 2×2, I've plugged everything in and even installed the midisport-firmware package which was not automatically installed for some reason.

The goal is to have the computer produce a piano sound when keys of the keyboard are hit. If you can make this work without jack, that would be good too. Step by step instructions, the less complexity the better.

OK I figured out the smallest number of steps to get this midi keyboard working:

  1. Install qsynth Install qsynth, Jack Control (called qjackctl) Install qjackctl, and download Claudio_Piano.rar from here, unpack and save in a handy place.

  2. Launch Jack Control (Applications > Sound and Video > JACK Control on older Ubuntu versions, or search for it in the Dash in newer Ubuntu versions)

  3. Click the settings button on the right side of the Jack Control panel, in the settings switch on midi input by going into the MIDI Driver drop down near the bottom of the window and selecting seq (alsa sequencer) and click OK.

  4. Load Qsynth, go into the setup, check Enable MIDI Input and turn the midi driver to alsa_seq, in the audio tab ensure the Audio Driver is set to jack, in the sound fonts tab open your downloaded sound font from above. Click ok and reset the server when it asks.

  5. If Qsynth freezes, unfreeze by stopping the jack server and then starting it again.

  6. Go back into the JACK Audio Connection Kit window and click Connect, here we are going to make sure in the Audio tab that qsynth is connected to the system output (drag handles).

    connect qsynth to output

    In the Alsa tab we are going to connect our midi device to qsynth.

    connect midi to qsynth

  7. Back in Qsynth Click on the Channels button and watch carefully all the little lights beside each of the midi channels. Press keys on your keyboard and see which one lights up. Click on that row and set the name to Piano (or whatever your musical instrument is)

  8. Play keyboard with sound output.
