The sliced-up audio can also be converted to REX files for playback and further treatment in Reason's Dr. Additionally, the software can automatically slice audio recordings into single notes or hits, for further creative control and to quantize a take, tweak timing to perfection, or drastically change the recording using time stretching. Automating MIDI equipment from Reason's sequencer or even from control voltages in the Reason rack is very simple to set up. MIDI is handled by an external MIDI instrument device, which is fully integrated into the Reason environment. The software includes MIDI-out support to bring the sound of hardware synthesizers and beat boxes to the Reason rack. Non-destructive time stretching allows for recording first and picking a tempo later, while non-destructive pitch change is done with a mouse click. A composite editor assists in building the perfect track simply by selecting the parts that work and muting the ones that don't. Users can record to an unlimited number of audio tracks, and record-ready channels can be created in an instant.

Reason 10 includes 5000 instrument patches, 1000+ mixing/mastering effects, and over 3000 loops. Additionally, the pitch editor allows for high-quality pitch correction from within the sequence window. The included Player Devices offer MIDI insert effects including scales & chords, note echo, and the dual arpeggiator. The software offers many workflow features including audio-to-MIDI, bounce in place, reverse MIDI, and split notes with the Razor tool. Version 10 introduces the Loop Supply and Drum Supply loop/sample sets, the Synchronous effects modulator, and six new virtual instruments, including the Grain and Europa synthesizers, Klang tuned percussion, Pangea world instruments, Humana vocal ensemble, and the Radical Piano premium acoustic piano.

The music production software Reason 10 from Propellerhead Software is a virtual studio offering synthesizers, samplers, drum machines, and effects, coupled with MIDI & audio tracks, and a dedicated mixer based on the world-class SSL 9000K recording console.
