Step 1: Download and Install Piano VFX Software

The download button on the piano-vfx website

First, go to and click “Download for Free” to get the latest version of Piano VFX. Extract the ZIP file, open the “PianoVFX” folder, and double click “pianovfx.exe” to launch the program. Currently, the program is only available for Windows.

At first, the interface may seem overwhelming. But I’ll guide you through the key features for creating a basic MIDI visualization.

Step 2: Set Up Your Piano Roll Visualization Project

The Settings of Piano-VFX's main section

Along the top row, pick an empty project slot. Name your project and click the save icon to store it there. This allows you to easily switch between different saved projects.

Next, import your MIDI file by clicking the folder icon and selecting the file. But what if you only have the audio file of the recording, and not the MIDI file? Well, Klangio’s Apps got you covered! Turn the recording of instruments into a MIDI file within just a couple seconds.

You can also add the matching audio track, so your video contains both visuals and sound. Other advanced options include:

  • Syncing a real piano performance video
  • Adding background images
  • Recording MIDI and audio in Piano VFX
  • Controlling LED panels on your keyboard

See Piano VFX’s manual for a detailed description of those features.

Step 3: Preview and Edit the MIDI in Piano VFX

Step 4: Customize the Piano Roll Visual Effects

Next, open the “Effects” menu to style your piano roll. The sliders adjust the Red, Green, Blue, and Alpha (brightness) levels.

For example, you can increase the brightness and make it colorful, then click “New Color Profile” and drag it into the first slot. In “Tile Color”, boost brightness more and mix in a nice shade.

Under “Note Hit FX”, select the “Partik” effect. Back in “FX Color 1”, you can raise the brightness again and tweak the hue. The results can look something like this:
