Play any synth or virtual instrument with your trusted guitar. ##### Lots of user videos: jamorigin.com ##### 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 comes as AudioUnit plugin (AUv3) and as a standalone app which can host other iOS synth apps or send virtual midi to Garageband or other DAWs. 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 website: www.jamorigin.com/docs or the user forum: jamosapien.com.
