MC-4 Hack is a software application that allows you to interact with the Roland MC-4 sequencer. It allows users to convert MIDI files into WAV audio files that can be loaded into the cassette input port of the MC-4 to program any of its four sequencer channels.
You can also edit sequences directly within MC-4 Hack, and preview them using your computer’s built in General MIDI instruments.
MC-4 Hack is available for both Macintosh and Windows systems, with a downloadable demo version available.
The software is built entirely with Max 5.1.9
