The Vestax PMC-580Pro can be operated in two essential ways: momentary mode or alternate mode. Momentary mode allows for instant effects with the push of a button. Alternate mode will apply an effect as soon as a button is pressed, and will continue until the button is pressed again. Basic effects include, pitch shift, distortion and mic echo. Program effects include loop, delay, reverb and more. The PMC-580Pro can link to a PC via its USB connection, and can output audio over SPDIF.
