CMP Grand Piano is a high quality virtual piano for your iPad, iPhone and iPod touch. It is designed for professional usage on stage by connecting an external MIDI keyboard to the iPad / iPhone / iPod touch by using the Apple USB camera adapter or another adapter supported by Apple.¹
CMP Grand Piano provides a very realistic sound by using a very large collection of audio samples of more than 1.7 Gigabyte (uncompressed) in size. Various articulations of each key of a real piano were sampled in full length and high quality to assemble this realistic sound. Real-time disk streaming is utilized to playback the respective audio samples with very low latency.
