Create more. Co-Composer is designed for Film, TV, and Game composers who want intuitive, touch-based control of their sample libraries and MIDI-based composition tools. • MIDI Keyswitch Buttons Import Logic Pro and Cubase Articulation Set / Expression Map files to build banks of corresponding keyswitch buttons with rich musical symbols and text labels. Or build banks of articulation buttons from scratch, save/load your banks as templates, or use pre-built templates for popular sample libraries. No more guessing MIDI note triggers. • Integration with Logic and Cubase - Co-Composer Focus Use in conjunction with the Co-Composer Focus Mac App to associate your projects' tracks to your Co-Composer articulation banks, so that track selection will automatically focus on the relevant articulation bank for fast, relevant key switching based on your project context. • Expressive CC Faders Set up to five pages of six large, responsive faders to control dynamics, expression, vibrato, or any other MIDI CC or Aftertouch. Or use any fader with 2 fingers to control pitch bend. Achieve nuanced performance without the need for expensive or unreliable hardware controllers. • On Screen MIDI Keyboard Use the on screen MIDI keyboard when away from your main workstation, or to quickly audition the chosen articulations without leaving the iPad screen. Continue shaping dynamics with fader while playing using multi touch. • Harmonic Modulation Assistant Instantly explore musical movement between chords. Choose a start and destination chord, and let Co-Composer suggest up to 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. Using with Co-Composer Focus on Logic Pro reads your project tempo to automatically keep your runs in sync with your composition. 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.
