Music software by Lionel Cohen · Los Angeles

Free tools for composers,
built by one.

A MIDI chord progression generator, a searchable catalog for your whole music library, and converters that reopen old Ableton sessions. Each one exists because a working composer needed it on a deadline.

Searching for one of these?

Here are the problems each tool was made to solve.

Free MIDI chord progression generator

Stuck on a blank project? Generate chords, a bassline and a melody in a chosen style and key, preview them, and export MIDI for Ableton, Logic, FL Studio or Cubase. Try the Sketchpad.

Ableton can’t find Kontakt 5

An older set opens but the Kontakt 5 device fails because the plugin is gone. The converter retargets it to Kontakt 6, 7 or 8 in a new copy. See Session Rescue.

Guitar Rig 5 missing in Live

Sessions that used Guitar Rig 5 FX can be pointed at Guitar Rig 6 FX without rebuilding every amp chain. Read how it works.

Catalog my music library

Turn a folder of tracks into one Excel file with instruments, vocals, mood, tempo, key and keywords. Meet the Music Analyzer.

Find the right cue for a brief

A music supervisor wants “tense, minimal, under two minutes.” Search every catalog at once, filter by BPM and key, and export a pitch shortlist.

Songwriting ideas in any style

Cinematic, Baroque, Bossa, Afrobeat, Synthwave and more. Lock the chords you like, re-roll the melody and keep going.

Questions

Which tools are free?

The MIDI Sketchpad and Session Rescue are free. The Music Analyzer is pay-what-you-like from $9, with a suggested $19, and there are free-access codes too.

Do they work on Windows?

The MIDI Sketchpad runs in any modern browser. The Music Analyzer has Mac and Windows installers. Session Rescue is Mac only.

Is my music uploaded anywhere?

No. The Music Analyzer analyzes audio on your own computer, and the MIDI Sketchpad runs entirely in your browser.

Will Session Rescue change my original Ableton file?

No. Every run writes a new .als copy next to the original. Listen to the copy before you archive the old session.
