The Logic Studio instruments cover almost every sound generation need you will encounter in your day to day work with Logic Pro and MainStage. All instruments feature intuitive interfaces that provide access to all functions and parameters. Pristine audio quality is assured when needed, or—at the other end of the spectrum—extremely harsh and dirty sounds can be created with many of the included instruments. All instruments are highly optimized for efficient CPU usage, maximizing the real time playback potential of your computer.
