The PS-3 contains both a pitch-shifter and a delay. There is seven pitch shift modes, and three delay modes as well as an expression mode. The pitch shift level is selectable in 26 steps – 24 chromatic steps over a +/- 1 octave range plus 2-octave up-down capability. The delay is up to a maximum of 2000 ms just like the DD-5.
