Read midi songs and play them with your PC keys or a midi keyboard. Select speed,instrument,volume, track...
Try using your left hand for notes that are at the left of middle C. I started learning with the right hand but
one day my left hand became alive and the brain talks to fingers, not hands
If you can't play notes that comes together (chords), just
press the Higher one.
First select the midi out on that list until it sounds pressing the q key on the pc to play a C note.
Next select song and press play. It will play all the tracks in the midi but only print the
melody track on the staff (you can select another tracks to see-play it's notes). Next you can use select the midi in port (in you have a midi keyboard).
Fallowing use another instrument, speed, volume, mute the melody.
You can use your midi keyboard volume control and pitch bend and modulation(CONTROL_CHANGE) wheels
There are 2 staff so you always see incomming notes.
Green color letters are sharps(#) so you must press the black key to the
right of the note
