The One and Only ACID
When it debuted in 1998, ACID Pro software launched a revolution in music creation. By offering a straightforward interface and "pick, paint, and play" interactivity, it was the first loop-based music creation application to put professional studio composition and editing power in the hands of producers at nearly every level of expertise. True to its revolutionary roots, ACID Pro 5 software is the power-user's application. New features such as Groove Mapping™ quantization tools, nestable folder tracks, native VST effects support, event reverse, and our patent-pending Media Manager technology allow for levels of music production unmatched in any other program.
