Here we talk about pro keyboards- all kinds of stage pianos, synths, workstations and digital pianos from Casio & Yamaha.

To be honest, there is not much comparison here with Yamaha pro keyboards definitely having an upper hand.
In fact, Casio does not have much presence in this area and have a long way to go.
What is a Digital Pro keyboard?
So how would you define a pro keyboard?
A pro keyboard is something that has all the tools that are required for creating and editing music, in case you are looking for keyboard for music production. And for arrangers, it need to have the best sounding styles based on various genres and the top sounding voices to match it.
Ease of use and a display that is intuitive is a must as it will be used a lot on-stage and you won’t have time to make a lot of changes in selections.
Most tech savvy musicians not only want the sounds to be cutting edge, they also want the looks to be inspiring, and some of the synths out there really look cool, with those hi-tech design.
Yamaha's most successful product is the Motif, and it tries to use most of its sounds on their other keyboards as well. Casio, on the other hand, has fewer offerings compared to Yamaha.
