The biggest problem with existing products is the limited range of material that can be processed without introducing objectionable distortion. If you play your instruments one note at a time then what's already out there may work for you. That is, if you can get mysterious settings like 'tracking' just right. When you work in the real world, plug-ins shouldn't be telling you what you can and can't do. Serato Pitch 'n Time has no confusing settings to tweak, and no nasty surprises. With Serato Pitch 'n Time you can process a wider variety of material than ever before, and always know you're going to get the best sound quality. Anything from a bass line to guitar chords to drums, or lead vocals, backing vocals, or even a complete stereo mix!
