Reason Studios, formerly known as Propellerhead Software, is a Swedish company known for developing Reason, a popular digital audio workstation (DAW). Founded in 1994, Reason Studios is best known for creating a highly flexible and modular music production environment, with a unique approach to combining virtual instruments, audio effects, and a rack-based interface that mimics traditional hardware setups.

Reason allows users to build custom setups with virtual synths, samplers, drum machines, and effect units, offering extensive possibilities for sound design and production. The DAW’s ReWire compatibility allows integration with other DAWs, while its Rack Extensions provide third-party developers a platform to create additional tools. Known for its creative freedom, powerful routing capabilities, and rich sound library, Reason Studios has garnered a dedicated following among producers, sound designers, and musicians. The company also offers Reason+, a subscription-based service that gives access to all of their software and sound libraries.
