MIDI notes in Scratch stands for Musial Instrument Digital Interfaces are musical notes that can be played on a computer or electronic device. They are written in the form of numbers and can be used to create melodies, rhythms, and sound effects. MIDI notes are represented by numbers.
The “play note ( ) for ( ) beats” block used the MIDI Note System. The note played by the “play note ( ) for ( ) beats” block with the pitch represented by the input given to this block as per the MIDI Note System and can be used to play the sequence of MIDI notes. By default, this block the notes of a piano, and the numbers of notes and beats are set to 60 and 0.25, respectively. When this block is selected and run, a graphic keyboard will appear on the screen.
In MIDI Note System, each note is selected either by using selecting or typing numbers or pressing the key on the virtual keyboard. The user can either select or type the number or press the key on the virtual keyboard to play a particular note.
As per the MIDI Note System, middle C is represented by 60. Adding or subtracting 1 from any number representing a key means moving one semitone higher or lower, respectively. Adding or subtracting 12 from any number representing a key means changing the particular note by one octave. In MIDI Note System, the higher the number, the higher the pitch of the note.
