Digital Ear Real Time. Live analogue to midi converter. Deuced clever technology, old chap. Listen to the demos. $129.95.
Digital Ear can analyze a live or recorded solo performance (e.g. a singing voice, a saxophone solo, or any other musical instrument) and convert it into a standard MIDI file! This file can be played by any synthesizer with a different voice of your choice, or you can import it into your favorite sequencer or notation software…The Real-time edition of Digital Ear can directly convert audio directly from the microphone into MIDI!
