WIth 8 stereo tracks that run synced together, or independently, this has the capability of 8 Line 6 DL4s stuck together! Designed out of a frustration with the live loopers available, this has an amazing amount of looping power, possibly more than anyone would need for even the most specific looping applications. With a MIDI pedal you can further control the unit, and there are a wide variety of overdub, reverse, speed and panning options for controlling the plethora of loops.
