“Envelope Follower to MIDI CC” is a Max/MSP patch and stand-alone application for converting audio files into MIDI CC messages in real-time. Just load an audio file, play it, and you’ll be sending MIDI CC data based upon the amplitude envelope of the audio file. You have controls over MIDI data scaling, sampling rate, audio playback speed, and strict playback duration for mapping projects.
The impetus for the tool comes from not being satisfied with available options to convert audio amplitude into MIDI data for Digital Audio Workstation mapping projects. As a teacher, I wanted to create a resource to enable student mapping that leverages their own digital tools.
I made the software available as a repository on github. You don’t need to Max/MSP to run; I made a basic stand-alone application as well and the link is included on github.
