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).

There are no perfect guitar to midi apps out there but this app gives you so much for so little. It’s down to your creativity and common sense to get the best out of the options and new worlds it opens to you. Plus there is immediate support at the end of Email. It’s changed so many things in music for me. Thank you and thank you!

Very impressive...

It’s great to see this extraordinary app get a 2019 update.

I tried this out on a whim and soon bought the in-app purchases (FYI you have to buy the 'Extras' add on before you can buy the 'control external instruments' one).

It would be unrealistic to expect to be able to play really fast lead lines with a guitar-to-MIDI setup, as some latency is imposed by the laws of physics, but melody lines are perfectly possible.
Polyphonic washes of strings/synths work really very well indeed.
I'm very glad to have discovered this app, and feel confident using it live gigging.

State of the art guitar 2 midi app

Really like this app. Having tried many routes to get my guitar as a midi controller including hex pickups and the like, I keep coming back to this app as it just works.

Great job guys and thanks 🙌🏻👍🏼😀
