Reason's interface is a virtual representation of what sequencers and synthesizers are really like, this means, we'll see the buttons, potentiometers, LEDs and other electronic elements on our screen. All of them totally functional.
Among the synthesizers we'll find Thor, Subtractor and Mälstrom among others. As well as dozens of samples like the NN-XT or NN-19. Reason is also compatible with various proprietary or very specific formats, as is the case of REX and FX2 files, even though it is possible to use WAV files by means of the Redrum rhythm box.
Reason will also work perfectly with any physical device like keyboards or MIDI controllers, for this purpose it includes several communication standards that guarantee that it will be compatible with the M-Audio, Akai and Doepfer controllers, to name a few.
Furthermore, modifying any sound by means of reverbs, delays, vocoders, filters, compressors and equalizers will be more than simple thanks to its intuitive menus.
Reason has a complete sequencer that can automate any parameter of any module, and it's compatible with the ReWire protocol (that allows us to communicate with another sequencer or sound studio).
On the other hand, the integration with Record (the other music software developed by the same company) guarantees a professional finish for any project without major problems. Something really interesting to have a real studio on our Mac.
