Reason is a loop-based music creation application with a focus on MIDI sequencing, sampling, and synthesis. What sets it apart from other audio software is its unique user interface, which emulates a virtual rack of audio hardware. It is highly technical and can present a daunting learning curve even for those with experience in other audio software, which makes recording engineer Bruce Williams the ideal guide. In Reason 4 Essential Training, Bruce explores every device in the rack, including the Transport panel, and the new devices like the ReGroove mixer, the Thor polyphonic synthesizer, and the RPG-8 arpeggiator. He also demonstrates production enhancements made possible by the revamped sequencer and automation interfaces. Exercise files accompany the course.
