Audio to MIDI Recorder automatically converts songs stored in your iTunes music library to MIDI files. Uses biologically-inspired algorithms to detect and segment musical notes.
What’s New in Version 5.0
Totally redesigned. New bio-inspired algorithms for automatic audio to polyphonic midi transcription.
Holy crap really? Sounds too good to be true. Check out the video!
Get Audio To Midi Recorder
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. Play any synth or virtual instrument with your trusted old guitar, or record tablature by playing it.
MIDI guitar is 8 years under development and based upon new advances in polyphonic pitch detection and prediction technology. It can accurately recognize guitar playing and articulation with very low latency and without spurious hits. The technology has been tested by thousands of beta testers.
What’s New in Version 2.1.3
MIDI Guitar 2 is finally here on iOS!
Everything is improved. Tracking in particular.
ATTENTION! old customers: Don’t upgrade yet if you have old iDevices (iPad2/3 or iPhone4)
ATTENTION! old customers: Please “Restore” your old purchase in the built-in shop.
MIDI Guitar uses Virtual MIDI to contorl other iOS synth apps or Garageband. It can also use WIFI-MIDI to communicate with Mac or PC digital audio workstations in a frictionless setup. Cable based MIDI to control hardware synths or connect to DAWs with lowest possible latency.
In order to use MIDI Guitar you need a iPhone 5, iPad 4, iPod 6 or later. You also 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 now and then, asking you to buy an in-app purchase. There are two in-app purchases. The first one gives you the full guitar rig and unlocks everything in the app EXCEPT the possibility to play external synths. For that you need the second in-app purchase, in addition.
Midi Guitar
MIDImorphosis is an app for polyphonic audio to MIDI conversion. Traditional MIDI converters for guitar and bass require custom pickups and expensive hardware. MIDImorphosis avoids this through advanced signal processing and adaptive algorithms, bringing polyphonic audio conversion to your iPhone, iPad, or iPod Touch. The app tracks both single notes and chords quickly and accurately. You can use any guitar or bass to control MIDI synthesizers or transcribe your playing automatically.
MIDImorphosis captures the pitch of incoming audio, and converts it into MIDI notes that can be used to control iOS synthesizers or external equipment. The app supports both monophonic and polyphonic playing; this version has dramatically improved chord detection.
With support for CoreMIDI, Virtual MIDI, DSMIDI Wifi, Audiobus, and background audio, connecting MIDImorphosis is a snap. Connections to laptop and desktop computers can be made using WiFi or with MIDI adapter cables.
The app is designed to work best with a guitar or bass. We recommend dock-based instrument adapters; connections through the headphone jack frequently have crosstalk and poor frequency response. We also recommend running MIDImorphosis on an iPhone4s or better, or an iPad2 or better (this is especially true when using Audiobus).
Complex sounds can be created by combining a typical guitar effects app along with MIDImorphosis and a synthesizer app. The guitar effects app can provide tone control and immediate response, while the synthesizer can augment this with a deep, evolving sound.
Musicians transcribing their work will find MIDImorphosis to be an invaluable tool. The app can send MIDI notes to notation software such as GuitarPro (desktop version only) and Progression (available for iOS).
In addition to live conversion, MIDImorphosis can also convert recordings into MIDI (avoiding latency issues). The app can record audio; audio can also be imported using either Audio Copy or iTunes File sharing. Audio can be exported with Audio Paste. MIDI can be exported to other apps using the “open in” feature, or through iTunes. The app also allows scanning through audio files, to see the detected pitch at any given moment; this feature should be particularly useful to musicians interested in transcribing a recording. Recorded audio and converted MIDI can be played back through the app. The app is compatible with the Audiobus input and output slots.
A number of videos are available on the app web page, to illustrate typical performance, and playing techniques to get the most out of the app. For guitarists, a light palm mute should be used to prevent unwanted notes from ringing. Pitch detection is typically best with the bridge pickup, and with a clean tone.
With any conversion system, there is latency between a note played on an instrument, and when the note can be correctly identified; the slight delay motivates the combination of guitar effects and synthesizers. MIDImorphosis should be fast enough to work well for playing at moderate speeds. For accurate note identification and pitch tracking, it’s critical to play “clean,” and to mute unwanted notes; you may have to adjust your playing style to get the best performance from the app. For guitarists in need of a system that can handle “shredding,” we would recommend hardware converters by companies such as Roland or Fishman.

Tim Behrens explains how he uses the audio to MIDI conversion in ThumbJam to play samples in Sampletank (it works for other programs, too).
Behrens notes:
I am not discouraging anyone from buying any apps here. Just showing how I use Thumbjam to achieve sounds close to what the dedicated midi conversion apps do.
For anyone who is serious about this kind of feature, I would recommend checking out the Midi Guitar app, as it is certainly tracks well and is polyphonic.
One last thing I’d say is that you have to practice with these apps. You can not just play your guitar like you normally do. Notes have to be muted more, there is a bit more latency, sustain will confuse it, vibrato jumps around. It takes time, but hopefully I demonstrated that you can get some very playable results.
Thumbjam is available in the AppStore for $8.99
