The OP-Z tape effect is used to do some interesting warping of the sound and time. Tape “rolls” continuously, capturing a segment of the performance. Through the speed and fine controls, that segment can be sped up, slowed down, and/or reversed. The relative tape loop start time, as well as length, can be controlled as well, using key button shortcuts on the OP-Z itself. The effect is controlled in real time using the encoders on the OP-Z.
