Allegro is a digital music sheet display and editor solution with a custom touchscreen display for symphonic studio recording. We develop a networked digital music sheet display attached to a stand, combined with a master server program controlling these devices. A typical network contains 60-80 pieces of 20-24” touchscreen music sheet display devices. Musicians can add personal comments to their own music sheets on their own device. The conductor can edit notes in the scores. These modifications are replicated by the software on each musician’s device. Turning pages will be controlled either automatically based on music tempo, or manually using touchscreen gestures. Development started in January 2016, live testing of MVP by a paying customer planned in Q3 2016.
