The s70xs and the s90xs are the identical internally so what I write here applies to both.

I own this keyboard (s70xs). The significantly vaunted s6 piano sound suffers from awful harmonics on the C#one, D1 and D#one keys. My previous keyboard (EX7) sounded fine by means of my Roland KC350 keyboard amp. The harmonics on these keys when played by way of the very same amp sound terrible, completely unusable in a live situation in my opinion. By means of headphones it sounds ‘OK’, not great but much more bearable.
The piano sounds also sound boring and muffled in my (and numerous other people) viewpoint.

It also drops notes like crazy when played reasonably quickly, even with a single voice like a piano selected. It also drops drum hits as properly if you have a drum track playing in the identical situation. I do not believe this is a polyphony situation, it simply does not function as it really should (other folks have reported the same problem). Once more, this helps make is unusable in a reside predicament. It really is not so great just playing at property either!

Modest screen size is not that a lot of an issue but they way some data is not displayed when it would make sense to do so makes some elements of making use of it more time consuming than it wants to be but otherwise it is usable.

Manuals are standard Yamaha which means rather terrible as far as really attempting to use them to do something ‘real’ but I suspect that problem is not restricted to this keyboard, my EX7 manuals are just as lousy.

Can’t use a altered voice in a efficiency without saving it initial. Tends to make it harder to just ‘try out’ distinct settings in a mix.

Other than that the keyboard is wonderful so it really is a shame that the above troubles with the harmonics and dropped notes make what should be a great keyboard into something that should be avoided.

My recommendation. Do not get this keyboard.
