A multi-channel effects processor from the 2000s with 249 DSP algorithms and flexible routing for professional audio work.
Overview
The Kurzweil KSP8 is a multi-bus signal processor built for professional engineers, producers, and musicians. Kurzweil sold it as a high-end effects system in the early 2000s. It handles mono, stereo, and 5.1 configurations. It can act as multiple stereo effects units at once, and it was praised for an intuitive design despite being complex at first.
