If you’ve ever seen a Yamaha Keyboard Synthesizer, you’ve noted that it looks very much like the usual arranger or musical keyboard. Few people realize that there’s much more to these instruments than meets the eye. Though they look like keyboards and most have 61 keys, Synthesizers are far superior musical instruments and thus more expensive. They can be used to create professional sounds and patterns, and also allow you to manipulate the various parameters of these built-in sounds. Synthesizers are professional instruments, used in recording studios, and do not have built-in accompaniment patterns, nor speakers. They are instead connected to the studio monitors.
