The SP1 88-Note Keyboard from Kurzweil is highly focused on simplicity and features a WYSIWYG (what you see is what you get) control panel and 256-voice polyphony. It is designed so you can spend more time playing and less time flipping through the manual.
Featuring sixteen programs in four instrument categories, the SP1 88-note keyboard is equipped with sounds from the Kurzweil sound library such as piano, electric piano, strings, pads, woodwinds, and basses. Effects include reverb, chorus, tremolo, and delay. Other features include: split, layer, layer/split, dual mode, and up to four simultaneous sounds.
Additionally, there is a dedicated external control section for sound sources that are connected via MIDI. Also, the keyboard has USB MIDI and MIDI in/out jacks for connecting to other MIDI keyboards or sound modules.
