Have the worlds most over-specced keyboard...

NEKO 64™ is the ultimate performance and studio instrument because it is simply the most advanced, flexible and cost effective product available today. Because it is based on our OpenSynth™ platform, NEKO 64™ frees you from all of the frustrating limitations imposed by closed, proprietary systems, while still maintaining the virtues of an all-in-one keyboard instrument.
