#Free virtual midi piano keyboard install#

Got it working too with ALSA: sudo apt install qsynthĪnd select /usr/share/sounds/sf2/FluidR3_GM.sf2. The sf2 instruments present by default on the VMPK GUI via Bank/Program pairs are the same as present in /usr/share/sounds/sf2/FluidR3_GM.sf2 as can be seen with: sf2text /usr/share/sounds/sf2/FluidR3_GM.sf2 | lessĮ.g.: (0 'Gun Shot' (preset 127) (bank 0) Use your computer mouse or keyboard to play the virtual piano keyboard (or the device touch screen for mobile users). So we connect the vmpk output to the FLUID Synth input with: aconnect 129:0 130:0Īnd fluidsynth starts producing some sound now as we touch the vmpk keys! The online piano keyboard simulates a real piano keyboard with 88 keyboard keys (Only five octaves for mobile users), a sustain pedal, ABC or DoReMe letter notes representation, zoom in and a full screen mode. Which gives: client 0: 'System' Ĭlient 128: 'VMPK Input' Ĭlient 129: 'VMPK Output' Ĭlient 130: 'FLUID Synth (586186)' Then I list all input and output alsa ports with: aconnect -l Then I can get some sound as follows: sudo apt install fluidsynthįluidsynth -a alsa /usr/share/sounds/sf2/FluidR3_GM.sf2 If you want to pipe ALSA output to another synthesizer of your choice, in the MIDI Setup you can set instead: Likely the relevant settings which make it work by default are:

I don't fully understand the details, but on Ubuntu 20.04 I just get sound out of the box from vmpk (not using Qsynth and JACK). Vmpk produces sound by default on Ubuntu 20.04 The primary difference is that you will be using a virtual keyboard rather than a physical keyboard, but patchage should not be able to tell the difference.

Virtually press any key in vmpk to hear soundĪlthough the specific tools in use differ slightly, you may find the guidance at Ubuntu Wiki helpful.

In Qsynth, load a soundfont from /usr/share/sounds/sf2/FluidR3_GM.sf2.

In patchage, connect Qsynth audio out to your audio interface (both left and right channels).

In patchage, connect vmpk MIDI out to Qsynth MIDI in.

Review JACK configuration to ensure it is attached to your preferred audio interface.

Install the 'patchage' and 'fluid-soundfont-gm' packages.

In your specific situation, where you want to use vmpk, qsynth, and jack control, I would recommend the following procedure to generate audio based on virtual keystrokes:

#Free virtual midi piano keyboard generator#

connect the audio output from the tone generator to the audio input for your monitors,.connect the MIDI output from vmpk to the MIDI input of some tone generator (e.g.Vmpk is a virtual MIDI Master keyboard, and does not produce any sound.
