Description Product Description Ideal for composing, recording, and combo use, Korg's intuitive Pa4X arranger keyboard really comes to life in the hands of the solo keyboard performer and entertainer. And nowhere else is the flawless operation and superior sound of one keyboard instrument more in the spotlight. To that end, every aspect of Korg's industry-leading Professional Arranger series has been re-examined and improved, resulting in the Pa4X - an instrument without equal. The EDS-X (Enhanced Definition Synthesis - Expanded) sound engine delivers unprecedented realism and highly detailed sounds, drawing on a massive PCM resource over 10 times larger than those found in previous models. Korg's exclusive DNC (Defined Nuance Control) provides highly-articulate solo instruments. Partnerships with Waves Audio and TC Helicon provide state-of-the-art audio processing and vocal effects. Plus, there are tons of instruments and drumkits, along with a massive infusion of Styles to cover a world of musical genres. The Pa4X Professional Arranger is more than a keyboard. It's your backup band, your accompanist, and your musical director. It's your soundman, your effects engineer, and your always in-tune background singers. Best of all - you're always in charge!
