At its core, reMIDI 4 is a powerful MIDI control tool designed to give producers and musicians precision and creativity. It takes MIDI files—the digital representations of musical notes and rhythms—and gives you complete control over them. Slice them, dice them, trigger them like individual drum hits or melodic phrases, and rearrange them to your heart's content. It's like being a DJ in your own digital record store, mixing melodies and beats to create something entirely new.
