Pro Mimics true hardware through a skeuomorphic GUI/UX
Reason's rack and mixer visually emulate real studio hardware through a skeuomorphic GUI/UX, allowing you to route audio cables and CV very intuitively. Hit "tab" on your computer keyboard, and you can see the rear of the rack, making routing very easy to understand.
Pro Offers an easy way to quantize and slice audio
Reason makes it easy to stretch audio or slice it up for glitchy sound effects. When audio is loaded, it is analyzed so slice markers can be placed at the beginning and end of each note. Slice markers appear when the audio sample is double clicked.
