Offering full-length, unlooped samples of every key for a spectacular piano sound, this new keyboard redefines your expectations for an instrument in this class. Taking its name from the Greek word meaning "color," Krome is the new standard for sonic excellence in a gigging musician’s keyboard, providing a limitless palette of sound to bring vivid inspiration your music. Introducing the Krome Music Workstation.

The original VOX Continental, a transistor organ that appeared in the 1960s, is a timeless classic beloved by top players as a practical keyboard with a home on any live stage. Now, a completely new keyboard that carries this concept into the present day has been again released by the VOX brand.
The VOX Continental uses a simple and intuitive interface that allows quick accessibility of every function. The high-quality sound engine section is centered on organ, electric piano, and acoustic piano, and provides a wealth of stage-ready sounds. In addition, the Continental features a powerful effects section to enhance these sounds, and even analog valve drive powered by Nutube, the cutting-edge vacuum tube. It's an instrument that perfectly fits your live performance requirements for a variety of styles including rock, pop, jazz, and more.
The air of tradition that emanates from VOX organs, together with the innovation of decades of research, down to the illuminated VOX logo shows the new VOX Continental is a fusion of both, redefining the existence of the modern stage keyboard.

*1: In rare cases, when a large number of processor-intensive effects are active simultaneously (for instance, more than 14 O-Verbs), polyphony may be slightly reduced.
*2: A portion of the multicore processor in KRONOS is devoted to generating voices, and a separate portion is devoted to generating effects. KRONOS dynamically allocates the voice processing power between the engines as necessary. The quoted maximum numbers of voices apply when 100% of the voice processing power is devoted to a single engine.
