One problem about the Casio PX 3 is that it uses the same samples as the cheaper Casio PX-130. In fact, it uses the same samples as the Casio PX-130 and Casio PX-330. Is it worth purchasing the Casio PX-3 then? I say no.
The Casio PX-3 is too expensive to be getting when you can get a similar product for half the price. The sampling loops are the same as the much cheaper Casio PX-130, and in fact, they still have not worked on fixing their incredibly short looping samples. It has constantly been a problem, but they still refuse to fix it.
Thankfully, they did fix the issues with the durability of their products. The keys especially were a big problem. The Casio PX-130 was the first step toward fixing it. The keys still feel plastic, but they are durable. Now, the keys are one area where the Casio PX-3 made an improvement above the Casio PX-130. However, they are the same exact action. It’s just made of different material.
Now, ask yourself. Is it worth spending twice as much on a new material coating for the keys? I say no.
