DigiTech Studio Vocalist EX Vocal Harmony Processor

Up to five-part harmony (original singer plus 4 other voices), large number of presets, create custom user presets, humanization control, built-in vocal effects, vocoder (keyboard control), sequencer control (computer via midi), chord recognition, etc. XLR input and output as well as 1/4" and midi 5 pin. Harmony processing by IVL of Canada. Very good cosmetically. Only typical scratches from mounting in rack cases. I used this in live performances controlled by a laptop running midi sequenced backing tracks one of which was the harmonies. Manual available online or I can email a pdf. Includes main box plus IEC power cord (internal power supply). Heavy duty build sturdy metal enclosure.
