Even some delay pedals and looper pedals use MIDI as a way to sync up timing across different effects. A lot of touring guitarists use MIDI-based foot controllers to select different effects and presets during their performance. Foot controllers often use MIDI to switch between different channels, banks and presets. MIDI can also be used to control different devices. Newer MIDI devices may use a USB port to connect to other MIDI devices so if a device doesn’t have the 5-pin ports, it may still be MIDI compatible. MIDI uses a 5-pin cable as shown to the right ( read this guide to learn about different types of audio/data cables).
The most common use of MIDI is with keyboards and digital pianos. A MIDI keyboard can connect to other devices to access different synths or samples.
MIDI (Musical Instrument Digital Interface) was created in the 80s as a way for musical instruments to connect and talk to each other. 8.1 Related Guides and Lessons: What is MIDI?
