It seems durable and was easy to put together. I had to order the bench separately because that’s not included. She’s been happily playing since receiving it, and I hope it lasts for years to come.
The electric piano and organ sounds were also very good. Brent particularly liked the B3 organ sound, and I thought the rotary-speaker sound effect added to the realism. Unfortunately, the harpsichord and string sounds were lackluster and disappointing, as the harpsichord’s note samples felt incomplete, and the strings sounded sterile and had a decidedly digital quality. But unless you’re experimenting with sounds, you’ll barely touch the harpsichord and strings, if at all.
It connects to the keyboard via Bluetooth , and through it you can easily adjust every parameter, including sound selection, volume, and metronome settings. In our most recent round of testing, all three testers ranked this keyboard first or second. The action on the CDP-S150—which Casio calls scaled hammer action—allows the keyboard to better emulate how the action feels across an acoustic piano’s keyboard, where the lower notes are a bit heavier than the higher notes. The keybed felt a little shallow, though, so overall I found the touch to be a bit light and lacking in the depth my fingers are used to, especially as my fingers got closer to the keyboard body . If you’ve already spent time playing an acoustic digital piano, playing the Roland FP-10 will feel closer to that experience than playing the Casio CDP-S150, which might be why two of our testers preferred its feel. We all said that its piano sound was better than the Casio’s, although only marginally.
Like the Casio, this Roland model lacks a digital display, but making adjustments manually is less intuitive on this piano. It displays volume via a series of lights that slowly get brighter and fill up as you press the button to make the volume louder, which is considerably less accurate and slower than turning the knob on the Casio. And although you can increase and decrease the metronome by 1 or 10 bpm at a time, there’s no way for you to know the exact value. A duet function allows the CDP-S150 to split into two sides so that a student and teacher can sit at the keyboard together, with each side covering the same range of notes. Some of our testers slightly preferred the Roland FP-10 over the Casio CDP-S150 for its more authentic piano feel and accurate sounds. It has Bluetooth to wirelessly connect to a mobile device running Roland’s Piano Partner 2 app, but its physical controls are far less intuitive than the CDP-S150’s.
Despite being the least expensive, it’s the only one of our picks that has a display, the button controls are simple, and it offers a duet mode for students and teachers to play together. It doesn’t sound or feel as realistic as our other picks, but it’s still a great choice for the price. The CDP-S150 has 10 total sounds, and the three grand piano sounds—standard, mellow, and bright—were the best of the bunch. I preferred the standard sound, but I can see uses for the other two when you’re playing with other instruments, either to sit back a bit in the texture with the mellow sound or to peek out a bit with the bright sound.
It definitely sounds electric, or rather like a recording of real instruments. The higher keys sound like a piano but the mid-range where we play most things sounds off. When you push dynamics the volume gets really quiet. The sustain softens the sound even more and doesn’t have a great sustain quality. The damper pedal is interesting but fair and I haven’t figured out what that middle pedal is supposed to do on this thing.
