Casio SA 46 is the cheapest and most basic digital piano that you can buy for your kids to learn how to play piano. Basically, the digital piano you want to buy to start somewhere. There is no easier piano to play than this one.

Casio SA 46’s design is smaller than others made by Casio. The reason for this is because Casio SA 46 only has 32 keys. The appearance is also a bit different since it’s a bit round on the edges. This design helps your kids stay safe when they’re using the piano. It’s not very sturdy but should be able to last for years.

Even though Casio SA 46 is compact, there are enough features to use. Even features from a more expensive piano are present. There are around 100 tones, more than most digital pianos on the market. Sound-wise, there is a distinct difference compared to more expensive pianos from Casio. This is to be expected of course since it is marketed for younger children who are just starting to learn piano. 

Besides tones, there are 8 polyphony notes. These notes can help you or your kid play more complex notes. 50 tracks will definitely help your kid to learn how to improve their rhythms and composition. 

Overall, Casio SA 46 is what you expect from a sub $50 digital piano. If you want to buy a digital piano so your kid can use it to learn but don’t have the budget for more expensive ones, or perhaps just simply not sure yet, then Casio SA 46 is a great buy for you.

Casio SA 78 Review

Casio SA 78 is priced at $54 and it comes with 44 mini keys, 100 tones, 50 rhythms, 10 integrated songs, 8 note polyphony, LCD screen, built-in speakers, headphone output and a switch between piano and organ modes.

Casio SA 78 is an amazing digital piano. It’s designed for kids who want to learn how to play piano. It’s fun, has a lot of features, portable with only 1.4kg of weight and can be used for a very long time. The 5 key drum pad is very useful to practice and has a lot of variety.

Casio SA 78 is bigger than SA 46 because it has 44 keys. Some people might think that it’s too big for a small child but on the bright side, when they grow up the piano would fit them better. 44 keys are right in the middle, not too big like a full 88 keys piano but also not too small. Kids with small hands would have no problem reaching the end of the piano and hit all the keys.

The control layout should be easy enough to use. If you have used Casio piano before, then you should have no problem using this once since the layout is the same. The buttons are marked based on their functions. There is also a small screen to make it easier to use the piano. The sides are curved to prevent children from bumping into it and hurt themselves. There are two built in speakers on the top side. 

As for the sounds, there are more than enough to play around with. These sound collections are very useful to help children learn piano and will be able to keep them entertained and motivated. The sounds can be accessed from the screen on the top. Navigating the menu should be easy enough, just like using a smartphone. 

There are 8 polyphonies available. Not many but not too little. Should be enough to help children learn. But there is also a concern about the lack of polyphony. You won’t be able to make or play a complex song with this digital piano. As for the sound, Casio SA 78 is okay. Compared to other digital pianos, Casio SA 78 is better but still can’t be compared with high end pianos. 

Overall, Casio SA 78 is a great buy for your kids. It’s cheap, safe, has a lot of features, and has 44 keys. Once again Casio proves themselves as the leading brand on digital piano.
