Not only does the LK-230 feature the helpful Step-Up learning system, in which the practice pieces are broken down into small learning units that are then learnt step by step; it also inspires musical creativity: The new Voice Pad function makes it really simple to play back voice samples and other sounds and effects using the pads. And that's not all; the LK-230 has plenty more to offer, including the AHL sound source boasting 48 notes, 150 rhythms, an extended automatic accompaniment feature with ON-bass chord and a large, easy-to-read display.
