Reason is a virtual studio rack with all the tools and instruments you need to turn your ideas into music.
Synthesizers, samplers, drum machine, REX file loop player, mastering tools, mixer, vocoder, effects, pattern sequencer and more. As many of each as your computer can handle. Reason is an all-in-one music production environment, complete with its own realtime sequencer.
Although easy to learn and use, Reason is a flexible music system - a system that can be just as complex and advanced as you make it, featuring numerous tools such as the MClass mastering suite, the Combinator device, and the powerful Thor synth.
Choose a synth, a drum machine, a loop player or any device from the Create menu, and it will instantly appear in your rack, logically patched into the signal chain. If you need more machines than you have mixer channels, just create another mixer.
Each unit in Reason's virtual rack is edited from its own on-screen front panel. All the sliders, knobs, buttons and functions are right in front of you, ready to be tweaked, turned and twisted in absolute real-time. And all your front panel actions - filter adjustments, pitch bending, gain riding or panning - can be recorded and automated in the Reason sequencer.
A single keypress will turn Reason's rack around to reveal "patch cord heaven". Most audio connections are made automatically. When a new device is created, it appears immediately below the currently selected device, and Reason patches it into the system in the most logical way. Repatch by dragging the patch cord plug to the desired connector, or just make a pop-up menu choice. Most devices have one or more parameters controlled by Gate and/or CV. And all instrument devices have several Gate or CV output options. Combine this with easy, transparent patching, and you have connection power approaching that of a fully modular synth.
The numerous included synths, samplers, effect, etc. are detailed here.
