I bought the Arturia Keystep, and I looked up on the website. There was no linux version of the driver/midi center. Any help?
If you are able to see your MIDI controller when you run:
then this guide should get you set up with the basics. It goes into quite a lot of detail and discusses possible errors you might face and I wouldn't want to skip anything or take credit away from it.
This command should display your controller:
You do not need WINE for any of this.
On Ubuntu 16.04, I then needed to do the following:
Add an audio group to run your software at the right priority:
sudo addgroup audio
Add yourself to the audio group:
sudo adduser $USER audio
Check what address your soundcard is on for output (it's usually hw:0):
Install Fluidsynth and a soundfont which will act as your synthesizer:
sudo apt-get install fluidsynth sudo apt-get install fluid-soundfont-gm
Install JACK2 which will be the sound server that sits on top of Alsa:
sudo apt-get install jackd2
Run the JACK server, but allow it to bypass any concurrent pulseaudio process:
pasuspender -- jackd -d alsa --device hw:0 --rate 44100 --period 1024
Run the synthesizer with one of the default sounds:
fluidsynth --server --audio-driver=jack --connect-jack-outputs /usr/share/sounds/sf2/FluidR3_GM.sf2
Now check what ports your servers are running on. This should display your MIDI controller(note the number after client, I got
And this should display the port for Fluidsynth(I got
Connect the two(remember
128 are for illustrative purposes, use the port numbers you see in the above two commands):
aconnect 129:0 128:0
You should now be able to hear sounds when hitting the keys on your controller!
