Originally, this functionality was achieved by writing shaders in ARB assembly language – a complex and unintuitive task. The OpenGL ARB created the OpenGL Shading Language to provide a more intuitive method for programming the graphics processing unit while maintaining the open standards advantage that has driven OpenGL throughout its history.
The virtual piano is played using a keyboard and/or mouse and typically comes with many features found on a digital piano. Virtual player piano software can simultaneously play MIDI / score music files, highlight the piano keys corresponding to the notes and highlight the sheet music notes.

It is intended to improve performance by offering low-level access to the GPU hardware for apps on iOS , iPadOS , macOS , and tvOS .

Without a matrix circuit, a 61-key keyboard for a digital piano or a computer keyboard might require 62 wires to connect (one for each key, and a ground)—an awkwardly thick bundle of wiring. With a matrix circuit, any of 61 keys can be determined with only 16 wires.
