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. The guitar-to-MIDI transcription runs in real-time, with latency and accuracy comparable to expensive and inconvenient hardware MIDI guitar solutions.

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. 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.

It will analyse your guitars playing in real-time and and know exactly what you play. As you can imagine, this opens up for a whole new dimension of guitar effects.

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).

In order to use MIDI Guitar you need guitar- or audio-interface. It will work with all types of guitars, but it performs best with a solid body electric guitar. Use a dry guitar signal, bridge pickup, tone all way up.

The app is free to try and evaluate with your setup.

If you have problems please see the built-in interactive help system or email our support.

I am considering buying but I am running into a recording issue

I am using Garage Band. I have used the trial to see how it works. I had one problem with the test drive. I get all the effects while playing but, it does not save the recording with the effects in Midi Guitar 2. I am apprehensive about purchasing until I know for sure it works on my mac. IS RECORDING DISABLED ONLY ON THE TEST DRIVE? Please let me know so I can buy it with confidence.

Borderline Magic

As someone who has lived thru a couple of decades real time pitch MIDI converters, this really pretty phenomenal piece of software!
