 The guitar can simultaneously drive a game system, an amplifier, headphones, a MIDI synthesizer, and music software via USB.The advantages of the guitar-like MIDI controller systems are that the tracking [the speed and accuracy of the notes the instrument produces] is much better than guitar-based systems, which means that there is no noticeable latency or pitch glitches.As well, whammy bars and other controllers can be assigned to any MIDI function, which gives the performer more on-stage control of their sound.
