Turn on, tune in, tweak out
The Kurzweil KSP8 multi-bus signal processor is an 8-channel effects system designed for the professional engineer, producer, or musician who requires high-performance effects, excellent sound quality, and unparalleled real-time control. It has over twice the processing power of KDFX, the world-class effects system found in Kurzweil's award-winning K2600 synthesizer. The KSP8 extends the arsenal of effect algorithms from KDFX, adding newly developed surround reverbs and many more stereo and mono algorithms. The architecture has enough flexibility and power to process up to 8 channels of audio simultaneously, in mono, stereo, and surround combinations. The power, flexibility, and sound of the KSP8 truly make it a must-have for professional and semi-pro studios, as well as for sound designers in search of exciting new timbres.

KSP8 architecture makes for easy effects chaining
The KSP8 architecture is elegant, offering a simple, easy to understand structure. On the lowest level is the effect algorithm. The KSP8 offers the highest quality algorithms designed for mono, stereo, and surround applications, with plenty of parameters for tweaking. From these algorithms, Kurzweil engineers have crafted exquisite effect presets ranging from spacious and gorgeous, to shocking and in your face rude. Effect presets are easily linked together to form effect chains on up to 8 buses. Users can fully customize effect presets and chains, giving users all the control they want. Manipulation and automation are a snap using MIDI or a host of local modulation sources including up to 36 LFOs and 36 envelope generators, with 72 functions available for combining control sources.
The highest level of the KSP8 architecture is called the studio. The studio is a kind of "snapshot" of the total state of the KSP8 at one time. Studios contain all the physical connection settings, signal routing (analog and digital I/O selections), analog and digital signal levels, as well as the assigned effect presets, effect chains, effect bus assignments (including all MIDI channel and controller settings) and all multi-band equalizer settings. A studio allows you to save and recall your entire project, quickly and easily. The KSP8 offers up to 999 locations for user-created objects. SmartMedia cards are used to store your work.
