DIRECTRE is an audio routing utility designed to work as a hub for a live performance using Propellerhead Reason. Directre’s audio switching synchronizes to the tempo of a song. With a press of a button, a channel switch is cued to open or close at the beginning of a measure, beat, or 1/8th note. DIRECTRE can function as either a 1×8 splitter device or as an 8×1 summing bus. In addition to the quantized switch capabilities, the switch can be adjusted to fade in and fade out with a touch of a button.
