MIDI, or Musical Instrument Digital Interface, is a protocol that allows electronic musical instruments to communicate with each other. It is used to synchronize the timing of different instruments, as well as to send control data such as pitch, volume, and panning.
The Boss RC-505 Loop Station is a powerful looping pedal that can be used to create and perform complex loops. It has a built-in MIDI sync function that allows it to be synchronized with other MIDI devices, such as drum machines, sequencers, and synthesizers. This allows you to create perfectly timed loops that are in sync with your other instruments.
