Playful tools for serious MIDI work.

We are excited to share our first macOS Application MIDISplitter. MIDISplitter helps you split tracks, rename parts, change instruments, audition ideas, adjust tempo, transpose, mix, and merge MIDI files without turning the workflow into homework. It's fast, fun, and full of production tools.

MIDI Splitter

Fast track cleanup before the creative part gets away.

Split tracks

Export every part into its own cleanly named .mid file, ready for a DAW, notation app, lesson, or collaborator.

Merge selected parts

Combine only the checked tracks into a fresh MIDI file when an arrangement needs a smaller, focused version.

Shape the sound

Change General MIDI instruments, balance track volumes, transpose, and try tempo ideas before exporting.

Audition before exporting

Listen to one track, selected tracks, or the whole file so the exported version matches what you meant to keep.
