Jordan Rudess recorded a performance on his GeoShred app, and then added some extra visuals.
This was a performance that was played live and screen captured. After that I added some extra visual effects. All the sound and all effects are created exclusively on my iPad with GeoShred. GeoShred is the most expressive iOS instrument in the world and can be played on iPhone or iPad.
GeoShred is also an MPE - MIDI controller as well as MIDI sound module. Perfect for using as a tone module with instruments like the Linnstrument, The Seaboard, The Continuum etc. The sounds in this video however are from the internal Physical Model sound engine.
