The definition of MIDI

MIDI is a very fundamental data format in the world of music production. While it does not contain any audio, it contains the information of what an instrument plays, i.e. which keys are played and at what velocity. It can also contain other information such as sustain pedal use. A MIDI file can both be recorded by the use of an electronic keyboard (or other devices supporting MIDI) but it can also be created manually in MIDI editing software (e.g., Logic Pro X which I use).

When a MIDI file is loaded into MIDI editing software you will be presented some sort of x-y-plot with keys on one axis and time (bars) on the other axis just as shown below.

How to use MIDI files with Synthesia

It is very easy to load your own MIDI files in Synthesia. First, you will need to download and install Synthesia from here: https://synthesiagame.com/. Then you need to purchase one or more MIDI files from my store (MIDI store).

In order to load your downloaded files in Synthesia you'll need to do the following:

  • Open Synthesia and navigate to 'Settings' from the front page.
  • Select the 'Songs' tab in the left panel.
  • Click the '+' to add the file path for where your downloads are located.
  • Go to the front page and click 'Play a song'.
  • Search for your song in the upper right corner
  • Click play!

      Hi Dustin! Thanks for posting. Unfortunately, I can’t guide you here :( MIDI files can be used in so many different ways… However, it is a standard format MIDI file, so you should be able to make it work. Try to post in a Yamaha-specific forum where people know more about Yamaha keyboards. It certainly has nothing do with whether you use Apple products or not, that I’m sure of :) Btw, if you purchased some of my MIDI files, and then don’t work then shoot me a mail and we’ll figure something out! Cheers, Jacob
