Although it isn't in the Ubuntu repositories so far (as of 19.04 Disco), it was easy to build from source on 18.04 (also, there is a pre-built Ubuntu.

I've got my eye on Polyphone as a (nearly) all-in-one solution (essentially a superset of qsynth+vmpk). The quickest way to experiment with changing settings is to close and restart vmpk to force a reconnect.Īlternative: "Polyphone" application (not in Ubuntu repositories) Vmpk loses its connection to Qsynth when the settings are changed. Presumably the are other settings that could also affect this. Qsynth -> Setup -> Audio -> Buffer Count : 8Īpparently, the CPU can't always keep up with the required burst rate, so a little extra buffering is needed to prevent underruns.Qsynth -> Setup -> Audio -> Buffer Size : 128.This led me to play around with some Qsynth Settings, and I found something that seems to solve both static/glitch problems (maybe with a trade-off of a minor latency increase): line glitching in and out in the Applications tab of Sound Preferences]. I later tried this setup on a less powerful CPU and noticed a similar static that did not seem to resolve over time. This static seems to affect all audio sources, but it somehow works itself out in a minute or two (at least partially). On both 16.04 and 18.04, I have experienced weird static when Qsynth initially starts working with alsa.

This was specifically tested on clean install of Ubuntu Studio 18.04, but similar steps worked for Ubuntu MATE 16.04, with a notable automatic configuration difference being that Qsynth -> Setup -> Audio -> Audio Driver defaulted to jack in Ubuntu Studio but to alsa on Ubuntu MATE. There is also a Panic button in case the reverb goes off the rails. From the Qsynth GUI you can manipulate the volume (see Gain) as well as Reverb/Chorus effects.

Input MIDI Connection : (Your Controller)Īt this point, you should be able to play notes from either your external MIDI controller or from the virtual piano GUI ( the GUI works even if you don't have an external controller).įrom the Keyboard GUI you can select different instruments (see Program).

Enable MIDI Thru on MIDI Output : (checked).

Virtual MIDI Piano Keyboard -> Edit -> Connections ->.

Qsynth -> Setup -> Sountfonts -> Open : FluidR3_GM.sf2.

sudo apt install qsynth vmpk # install components Here's the simplest way that I have found. It's nice to have a low-complexity solution working before you bother with optimizations, but unfortunately Ubuntu doesn't come with a default working configuration. MIDI on Linux is highly modular and, as a result, initially overwhelming. I have also once written an article on general workflow for music production with external keyboard on Ubuntu, it should be useful in your case. All synthesizers provide you lots of customisation, it's worth to spend some time choosing what you like most. In case of ZynAddSubFX, this will be a plain sine wave, boring! However, you can easily browse a great collection of timbres, and you can customize them fully. You will most likely not enjoy the initial sound of the synthesizer. Also, some synthesizers require you to choose an instrument before they produce any sound.įine tune your synthesizer settings. You will hear some sound! If not, make sure if your system sound is not muted, and that our speakers are connected. Once you connect your keyboard, and synthesizer, follow to the final step.

While aconnect is installed by default, you can get the other two from Software Center. You can either use aconnect tool, or one of it's graphical backends (which are simpler to use), like aconnectgui or kaconnect.

You need to create a link between your keyboard and your synthesizer, so that MIDI signal is passed to it. Tell the system to pass data from your keyboard to the synthesizer. Of course it has to be running to produce sound. Make sure to browse Ubuntu Software Center for synthesizer that will grab your interest. You may like ZynAddSubFX (really powerful one), FluidSynth or QSynth (support soundfonts), AMSynth, AMS. There is a large variety of sound synthesing applications for Ubuntu.

If that's a USB MIDI keyboard, just plug the USB, if it has only MIDI plug, you may want to use a MIDI to USB device.ĭownload/Install a synthesizer. Plug in your MIDI device to your computer. These tools are great if you want to record MIDI signal, write notes, and route audio between separate applications, but you don't need that to play sound with your keyborard. If you just want to get your keyboard to play sound, this is very simple, and you won't need JACK nor Rosegarden for that.
