In order to use MIDI Guitar you need guitar- or audio-interface.
MIDI Guitar for Garageband is very easy to set up (it just works) but it has some limitations compared to the more expensive plugin version of MIDI Guitar (more info at our website).
As you can imagine, this opens up for a whole new dimension of guitar effects. It will analyse your guitars playing in real-time and and know exactly what you play. It can be used with MainStage or Logic as well, using Apple's Virtual MIDI standard, or even hardware synths with good old MIDI cables. MIDI Guitar for GarageBand is meant to be used with Garageband's virtual instruments but it is also a powerful and versatile guitar effect processor on its own. The guitar-to-MIDI transcription runs in real-time, with latency and accuracy comparable to expensive and inconvenient hardware MIDI guitar solutions. MIDI Guitar is a revolutionary piece of software that allows you to play software instruments and synths on your guitar, essentially converting your guitar into a polyphonic MIDI controller/keyboard. Play any synth or virtual instrument on your guitar!
