🚀 Getting Started

First let's install the required python libraries. Open up a terminal and enter these lines:
```
pip3 install mido
pip3 install python-rtmidi
```

Now we can start the program:

python3 /PATH_TO/MIDI-Maestro/main.py

You should see:

Started a virtual MIDI port called 'MIDI Maestro'.
Set the input of your VST instrument to this port.

Open your VST instrument of choice. Set the input of the instrument to "MIDI Maestro".
Back in your terminal you should see something like:
```
Available MIDI ports:

    [1] KeyLab mkII 88 MIDI

Select a MIDI input port (1-1):
```
Type in the number of your keyboard port and hit ENTER.

Select the piece you wish to play the same way as before:

Available pieces:

    [1] Chopin - Prelude No 4

Select a piece (1-1): 1
Using piece 'Chopin - Prelude No 4'

Start playing... (CTRL+C to cancel)

Now just start playing!

🎵 Adding more pieces

You can add more pieces as MIDI files. Simply copy your MIDI file into the MIDI-Maestro/MIDI folder.

Pieces that work best:

Easy rhythm
Similar rhythm all the way through
No trills or other ornaments
Mostly legato (staccato doesn't work unless you play fast)

You can of course use any piece you like.

If your file has a different extension than .midi (e.g. .mid, .MIDI, .MID) you'll need to rename it.

Depending on the way the MIDI file is formatted it might not work as expected (MIDI files from MuseScore are known to have issues). You can try importing the MIDI file into your DAW and exporting it again. MIDI files of type 0 with a high resolution work best.

If you find that some notes are played together instead of individually or vice versa, you can try tuning the SENSITIVITY at the top of main.py.
