KeyStage is a master controller app designed mainly for keyboard players. With KeyStage, you can simultaneously control any number of hardware and software instruments using any number of MIDI controllers in an organized way.

Each project consists of sections (which corresponds to sections of a song). In each section you can change sounds and sound parameters of connected instruments, create complex splits and layers of your keyboard(s), change the functionalities of sliders/knobs/pedals of your MIDI controllers by creating advanced MIDI mappings, view PDF and JPG files (e.g. sheet music) and lyrics, and much more.

The live console of KeyStage is optimized for live performances. For each section, you can view one of the five live units in the live console:

1.\tInfo Unit, which show an overview of the section including the keyboard ranges, volumes and pitch translations of each instrument
2.\tXY Touch Surface, where you can assign control change or pitch bend parameters to x and y axis
3.\tLyrics Unit, where you can show the lyrics for the section
4.\tMedia Unit, where you can view PDF and JPG files
5.\tPiano Unit, which is a virtual MIDI piano with a pitch bend
