Roland VP-9000 Variphrase Processor equipped with Variphrase Technology. Using a microphone to directly record vocals or sounds recorded from various audio sources, you can freely control them in real-time with three controls (PITCH, TIME, FORMANT/GROOVE) and MIDI. I have owned this instrument for a long time, but I haven't mastered all of its functions, so I haven't been able to test it. If you are considering purchasing it, please keep this in mind. I can only say that the condition is good, so I recommend thoroughly testing it once you receive it.
