After seeing this video I wanted to do the same, but using my programming skills and being atomatise the task. On account of the idea of the code being public I uploaded a demo video and another explaining it on a youtube channel before creating jensenProgramming.

Usage

All the work that needs to be done is on Main.java.

First a general Program Folder must be set on line 19. Where all the data will be stored.

public static final String FOLDER_PATH = System.getProperty("user.home")+"\\Documents\\Midi Tuner Stuff\\Midi Tuner 2\\";

Then on line 35, MIDI_PATH will contain the path of the midi that will be used.

On line 52 the instruments used will be specified. If the midi has 4 tracks, 4 instruments will have to be specified.

instrumentNames = new String[]{"guitar","guitar","guitar","guitar"};

Lastly, to change the velocity of the played midi, k must be changed on line 54.

Getting the data prepared

As this isn't a pich shifter, every instrument will be required to have a folder with its name, photograms of every note as well as the audio of the notes. Aditionally, a photo with the name no-instrument.jpg will be needed when there is no instrument playing.

You can get the data I've used here. You have to use the same structure.
