The keyboard arranger has become a really popular choice for professionals and beginners alike. The sound quality and convenience of today's arrangers will blow you away. There are several features you want to pay attention to as you are shopping for a keyboard arranger. Most arrangers have built-in speakers, but some will require you to plug into a separate sound system. A full length keyboard has 88 keys, but many people choose to save space (and money) by going with a smaller 61-key or 76-key model. Look for "weighted" keys if you like the feel of a real piano. Most of today's arrangers come with hundreds of amazing sounds. Some additional features to consider are whether you want backing tracks like drums and accompaniment, a built-in sequencer to record your work, USB ports to connect to your computer, or microphone and guitar inputs. We hope this helps a little as you shop for the best keyboard arranger for your style.
