MIDI Guitar is the World’s first app to transcribe guitar playing into MIDI in real-time, with latency and accuracy comparable to expensive and inconvenient hardware MIDI guitar solutions.

MIDI Guitar is over 10 years in development(!) and based upon state-of-the-art polyphonic pitch detection and –prediction technology that can accurately recognize guitar playing and -articulation with very low latency and without spurious hits. The technology has been validated by thousands of guitarists over the years.

MIDI Guitar use Virtual MIDI to drive other iOS synth apps or Garageband, and it can host AudioUnit synths and effects.

You need a guitar interface for best results. We recommend a digital interface (using the lightning connector) over analog (via headphone jack), preferably with input gain control. Using an acoustic guitar with the built in microphone works for some purposes but is not optimal.

The free version will interrupt every few minutes, asking you to buy an in-app purchase.

If you have problems please refer to the built-in interactive help system, browse our website: or email our support (via the contact form on our website).

One of the best apps ever created

I’ve been playing around with this app for a few years now. More as a fun curiosity. Had it on stage a couple of times but things were getting too cluttered with the phone rigged up with MIDI Guitar 2 and pedals. Was looking more at trying to slim down all the wiring on stage. I just discovered all that’s under the hood in this app today. I can actually get rid of all my pedals (except one) and use MG2 exclusively. It’s equipped with all the effects I normally use in pedal form. Plus all the virtual instruments I want to use - so no other app is necessary. I already thought this was a well above the mark app, but now.....! This plus the Omec Teleport and l’m totally set. You can set presets in the app for all the sounds + effects combos you use. So easy to get a setup you like, then save it and recall when you need it. Thank you so much. This is truly the best note to MIDI converter setup ever devised. Either the tracking has gotten better over the past year or I’m getting better at playing through a MIDI converter. I can barely hear the latency. Sounds more like a slight quick single hit delay effect (quick slapback) - which I normally use anyway. Soooo awesooooome!!!

Well I had written a few paragraphs and lost my review. I don’t write reviews. This app is unreal. I had a Fender Strat with an integrated Roland Pickup in the 90’s. It connected to a MIDI controller which connected to a synth module. It was cool but the delay between plucking the string and the MIDI translation was unpleasant.
Needless to say the delay if any with this app is imperceptible. Your guitar and an IOS interface, that’s it.
This app is truly an awe inspiring piece of software technology. I really can’t say enough. Download it! Demo it for free. There are three purchase options. It’s worth ten times as much. If you like making music this will change how you play guitar forever. Saxophones and flutes? Yeah that’s cool but synths... pads, arpeggios, keys, all layered. All of the sounds man!! It’s unreal!! Awesome job. Keep going. You have created magic. Over the top clearly.

It actually works

Like many who are proficient at an instrument learning to master another has its challenges. Starting from scratch on a keyboard when I can easily play a song on my guitar gets boring. Quick. And though I can use a keyboard recording in real time is difficult at best. Throw in the fact I own many apps with tablature and few with piano notes this was the app for me. Now when I need that quick sax or flute. There it is. All I gotta do is what I do. Play guitar. As far as some reviews saying the chords sometimes sound muddy. I play the chords as if I’m playing a keyboard. I.e. I pluck the three (or more) strings that make up the chord. Not strum all six guitar strings. Really great app. Easy to use. Thinking of buying the computer version at some point. Good job developer.
