Reason is a DAW made by Propellerheads and can be found at www.propellerheads.se. Reason costs $399.00 and comes with 10 software instruments. Reason Essentials includes six software instruments and costs $99.99. A prerequisite for rewiring is to have purchased Reason and have it installed on your computer.

Reason's greatest advantage is that it includes remarkable high-quality software synthesizers and drum samplers. However, the interface for creating and building your song with FL Studio is a bit faster, more intuitive, and has a more capable Piano roll. Consequently, rewiring Reason means that you can simply hijack the software synths and samplers in Reason, but continue to use FL Studio as a sequencer and mixer. We are basically telling Reason that we don't care about their program; we are, however, very impressed with their virtual instruments. The purpose of rewiring is to still use FL Studio's step sequencer, Piano roll, and ease of composing.
