MIDI Guitar is a revolutionary piece of software that converts your bass guitars analog audio signal into a digital MIDI signal. This makes it possible to use your standard guitar as you would use a MIDI keyboard or MIDI controller. You can use this to play your favorite software synthesizers/samplers with your bass guitar, rather than a keyboard or record notation directly in recording software (digital audio workstations).
Traditionally bassists have had to seek out expensive and inconvenient hardware to be able to use a bass guitar as a MIDI controller. MIDI Bass removes the need for any kind of specialized hardware beside a standard guitar interface to connect your guitar to your computer. Just connect your guitar and let MIDI Bass do the rest. MIDI Bass is based on state-of-the-art audio recognition which is even more responsive than many hardware solutions, however, unlike the polyphonic MIDI Guitar, MIDI Bass is monophonic for now, meaning that you cannot play chords and have to be a bit careful with open strings.
MIDI Bass comes in a few variants: as standalone Windows/Mac standalone applications that can host VST/AudioUnit instruments and effects or as VST/AudioUnit plugins that can be hosted inside your favorite Digital Audio Workstation (DAW) software.
