Reason by PropellerHead Software is one of the most powerful music creation softwares around. I have been using reason since the days of Reason 3 and it’s one of those things that can never get boring.
Reason’s approach to music creation will feel a bit different at first if you are used to composing in programs like FL Studio, but a welcoming change in my opinion. Reason is designed around the concept of using modules to “create” your synths and effects much like you woul have racks in a physical sense.
