Kurzweil's SP4-8 is the modern successor to our best selling SP88/X, which famously combined world-class Kurzweil sound quality with previously unheard of affordability and portability.

The updated SP4-8 makes available to more players than ever the same sound set featured in our hugely successful PC3 line of professional keyboards, in an instrument that is slim, lightweight and extremely easy to use.
