Used as a conventional delay machine, the SDD-2000 can provide very long delay times of up to 4368ms. Up to 64 effects such as chorus, flanging, doubling, and echo can be programmed for easy access. The sequencer and sampling modes allow audio inputs of 4368ms to be recorded and then reproduced when desired. Coupled with a MIDI keyboard or controller, the sampled sound can be played like on a sampling keyboard. Tempo and program select can be triggered via MIDI.
