Compose faster. Create more. Co-Composer is an iPad companion app designed for Film, TV, and Game composers who want intuitive, touch-based control of their sample libraries. • MIDI Keyswitch Buttons Use templates or import articulation set files from Logic Pro or Expression Map files from Cubase to build banks of articulation keyswitch buttons automatically. Or build your own from scratch! No more guessing MIDI note triggers. • Integration with Logic - Co-Composer Focus Use in conjunction with the Co-Composer Focus Mac App to map your logic sessions' tracks and assign your Co-Composer articulation banks to them. Then track selections will automatically focus on the relevant articulation bank. • Expressive CC Faders Set up to six large, responsive faders to control dynamics, expression, vibrato, or any other MIDI CC. Achieve nuanced performance without the need for expensive or unreliable hardware controllers. • Harmonic Modulation Assistant Instantly explore musical movement between chords. Choose a start and destination chord, and let Co-Composer suggest 1–4 pivot chords across nine “flavours” of colour and chromaticism — from smooth to adventurous. • Runs Composer Build a melodic run from a number of melodic shapes and harmonic modes and scales by start and end note. Hold down on the run to play it at your chosen tempo straight to your DAW for a fast, one-touch run in your compositions. Whether you’re sketching themes, recording expressive mockups, or exploring new harmonic pathways, Co-Composer keeps you in the creative flow by making articulation switching, CC shaping, and modulation exploration fast, visual, and musical. Disclaimer & Thanks Co-Composer is a vibe-coded passion project by a composer, to make everyday scoring more efficient. Updates and improvements will be provided on a best-endeavours basis, but ongoing support is not guaranteed as part of your purchase.
