Most modern keyboards feature a USB Type B port, while some older keyboards and pro-grade instruments use a MIDI connection (dedicated MIDI In/Out ports). You can also use them to control various music-making and learning apps (more on that in the following sections). When you press a key on your keyboard, a sustain pedal, or use any other controller that your instrument has, you generate MIDI messages that tell which key was pressed, how much pressure was used for it, how long a note was held, etc.Īll these messages can be sent to your computer and recorded as a MIDI file. Note: MIDI (Musical Instrument Digital Interface) is a protocol that allows computers and electronic musical instruments to communicate with each other.
