Over the last couple of weeks I have demoed the Casio WK-110 and Yamaha NP-30. My impression of both was surprising to me.
The NL-30 looks good, has 76 keys, weighs 12 lbs, has midi and several sounds.
To me, the feel of the keys was not pleasant nor was the piano sound. Actually none of the sounds impressed me in other than a negative way.
I remember seeing a post someplace that through external speakers it sounded as good as any of the other Yamaha keyboards.
However the sound of the PSR-E403 sitting right next to it was much better.
It may be ok as a midi keyboard controller, if you like the keys.
At $299, I think this will be a sleeper for Yamaha, especially when compared to the WK-110 for $100 less.
This was a major surprise for me, as I have never been a fan of Casio. This keyboard is attractive to the eye, weighs 15 lbs, has a pretty good key feel, but most importantly the sounds. The sounds that interest me anyway are quite good. Much better than the NP-30.
The piano, vibes, funk piano, and some others, I didn't try them all, were really outstanding. This thing will sell like mad to all categories of players, IMHO.
The rhythms were very well constructed, although the tonal quality from what I could tell in the little that I checked out that feature didn't sound as good as the PSR's.
For $199 I can see this as a good keyboard for beginner piano students, to take along on a trip, for an arranger keyboardist who wants 76 keys to improve his piano chops and I feel that we will see a number of these pop up in public on piano gigs. Yep, you heard me correctly. I am seriously thinking of getting one myself for when I am playing piano in a 10 piece band where I don't need all the other stuff on my Tyros 2.
One major con on the WK-110 is it only has USB to midi. As I understand it, it will not work as a midi keyboard controller.
Both keyboards just have a headphone jack for output.
I will probably test them both out with my speakers when I have time to see how they sound that way.
Here is a clip I found on YouTube on the Casio. I wish I knew what these people were saying, but I don't speak Spanish. The interesting thing to note here is that it appears to be a TV show and it's set up in a band who is using what appears to be Marshall stacks or something on that order. Normally a very unlikely combination
It is obvious though that at the end of the guy talking about and playing the WK-110, he has both thumbs up.
Don't bypass at least trying the WK-110. I think for what it is, it will surprise you too.
