Hum2MIDI — App Overview
In one line
Just hum, and your melody is converted to MIDI — ready to edit and export.
Overview
Hum2MIDI detects pitch from your microphone in real time and converts it into MIDI notes. Even if you can't play an instrument, you can capture any melody that pops into your head as musical data (MIDI), edit it on a piano roll, and export or share it as a standard MIDI file. Perfect for brainstorming composition ideas and getting something into your DAW fast.
