The JAX Xcelsior, one of our Concert Grand Piano Collection pianos is a virtual piano (sound module and audio unit) with a set of selected largest piano models.

The very special here is optimization for mobile devices, because it is using low resources while it delivers still better sonic qualities than gigabyte heavy sampled pianos, which mostly are not very well suted for mobile devices due to ther enormous usage of disk space and memory. A JAX Concert Grand will merely use around 50 to 100 MB of effective memory with a selected model.

For the series we developed some advanced features (i.e. simulation of string and body resonances) and took special care of expressivity without rasterized steps in the velocity of max. 128 possible values. An artefakt you often will hear with sampled pianos is velocity switching, because sampled velocity layers are usually insufficient for supporting the full dynamic range of a real piano.

The Superior was the very first release of more to come with this series: For instance our set of American style (Imperior) and Japanese style (Emporeor) Grand Concert Pianos, the Xcelsior (Largest Grands) and the Xperior (Selected Grands), which all have quite differend but well known sound characteristics. There are at least 4 different base models available with each of the releases plus a set of 16 hybrid models, which are fusions of the base models and all are selectable with just a touch for any performance. So all in all, there are 20 different timbres for instant selection availble with each of our Concert Grands (in sum 20 different, unique base timbres and their 16 fusion models ( = 100 !!! ).

The JAX Concert Grands mainly were created for performing classical music of all decades and Jazz and also come with its own integrated MIDI player, which is able to perform real MIDI recordings with sample accurate timing precision. Hundereds of such live played performances are included for enjoyment and audition, covering all famous piano componists of the last centuries. Each model has its own selection of MIDI files for random playing.

We specifically optimized the user interface for usage on the iPhone and the iPad.The macOS versions are identical to the iOS versions and optimized for the big Mac displays.

This build is truly 'universal', meaning, unit is available for:

- MacOS (Catalyst)
- MacOS (Apple Silicon)
- iPadOS (iPads)
- iOS (iPhone)

The JAX Concert Grands feature different models of high quality virtual pianos.
JAX series releases are AudioUnits (AUv3). Audio units usually require a supporting host application for operation.
The main app also allows MIDI live connections for direct playing as a sound module.
