SOS’s Paul White got this demo of the new Yamaha S70 XS synthesizer at LIMS 2009:
Just in from Yamaha are the S70XS and S90XS performance keyboards. They both run on the same operating system, the only difference being the size of the key beds: the S70XS has 76 keys, while the S90XS has 88.
Both models have weighted, hammer-action keys so, even on the smaller model, users get the feel of a real piano.
On-board controls have been simplified by Yamaha so that only the most commonly used features are available to the user from the button-driven interface. This, the manufacturers say, provdies a less cluttered menu system that lets users access the most important parameters quickly and easily while on stage.
