.MX4 File Extension
File TypeMixcraft 4 Audio Project
What is an MX4 file?
Audio project created by Mixcraft 4, a multi-track software recording studio; may include loops, references to audio files, transitions, and effects; used for creating musical compositions.
While MX4 files may contain MIDI audio data, they do not store associated audio files such as .WAV files. Therefore, to transfer a Mixcraft 4 project between computers, you have to copy the associated audio files as well.
NOTE: Mixcraft 5 uses the .MX5 extension to store audio projects. Mixcraft 5 can still open Mixcraft 4 projects.
