Reason Studios (formerly known as Propellerhead Software) is a music software company, based in Stockholm, Sweden. Founded in 1994, it develops the studio emulation digital audio workstation Reason.
Propellerhead Software was founded in 1994 by Ernst Nathorst-Böös, Marcus Zetterquist and Peter Jubel, who still hold prominent positions within the company. Their first release was ReCycle, a sample loop editor that could change the tempo of a loop without affecting the pitch. The export medium was Propellerhead's own REX format. ReCycle was launched in conjunction with Steinberg, who marketed it as a companion to Cubase, as it brought a simple way of gaining control over tempo and timing of audio loops.
In 1997, Propellerhead released ReBirth RB-338, a step based, programmable sequencer which emulated classic Roland instruments commonly associated with techno: two TB-303 Bass Line synthesizers and a TR-808. A TR-909 drum machine was added in version 2.0. It was hailed as an affordable alternative to buying old, unreliable hardware devices. Roland Corporation requested that an acknowledgment be added to the ReBirth packaging and splash screen; the unofficial endorsement became a marketing boost for Propellerhead, and they have retained a close relationship with Roland ever since.
ReWire was developed jointly between Propellerhead and Steinberg for use with their Cubase sequencer. Released in 1998, it provided a virtual audio and synchronization connection between Cubase and ReBirth. In January 1999 the protocol was opened for general use by third parties without any license fee, to allow communication between different sequencers.
Propellerhead soon focused their attention on their new product, the award-winning digital audio workstation; Reason. It first released in 2000.
In May 2009, Propellerhead announced a new product, Record. Designed for recording, arrangement and mixing, Record is made along the lines of Reason and continues the tradition of emulating hardware and the rack.
