The Genevoice GM64Pro24 bank contains 2 banks of 128 GM compatible melodic instruments each (256 total) and 11 XG compatible drum sets. The bank is compatible with 24-bit as well as 16 bit soundcards, hardware and software synthesizers. 24-bit quality allows approximately +6db dynamic range increase compared to 16-bit, which delivers large amount of extra details in a sound of instruments. Users of the new 24-bit capable hardware can enjoy the higher fidelity sound when playing standard midi-files. But other 16-bit hardware and software synthesizers will render the Genevoice GM64Pro24 bank in 16-bit quality, still delivering the brilliant quality of its samples.
