Gestrument Pro is a multimedia application available on iPhone that allows users to create music based on complex systems of musical rules and interactions. With the ability to play, improvise, and compose using the motion of your fingertips, Gestrument Pro offers a unique and deep level of personal expression.

This application is designed to bridge the gap between a bespoke instrument and a written piece of music, allowing users to play their own music in their own way. It offers a modular system of highly tweakable musical generators, enabling experimentation with simple and advanced musical concepts such as microtonality and polyrhythms.

One of the standout features of Gestrument Pro is its improvisational capabilities. By building patches based on the musical rules and properties of your own music, you can improvise in real-time. The Pitch and Rhythm generators ensure that you're always on time and on pitch, regardless of how you play.

Powered by the revolutionary Gestrument Engine, Gestrument Pro brings together the expertise of award-winning composer Jesper Nordin and leading iOS developer Jonatan Liljedahl. This app builds upon the original Gestrument app from 2012, offering new features such as multi-touch support, recordable automations, advanced scale editing, and a unique system of highly tweakable modular generators for rhythms and pitches.

With up to 16 individual instruments, each controlled by up to 8 cursors, Gestrument Pro provides a flexible and customizable musical experience. It supports internal high-quality sounds, as well as the ability to play other synthesizers or apps via MIDI. The app also supports Inter-App Audio and Audiobus, including host sync for following the host's transport and tempo.

Gestrument Pro is a free app available on the App Store and offers a wide range of features for musicians and composers looking to explore new musical possibilities.
