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 (e.g. Cubase VST, Cakewalk, Sonar, Logic etc.) for mixing with other tracks, automatic transcription, or any further processing.
