The Smart Scaled Hammer Action Keyboard is present here once again and was actually first introduced with the PX-S1000 and PX-S3000. This key action was well received upon its release, and is known for being pretty down the middle in terms of weighting – not too light and not too heavy.

To accommodate the super slim case, Casio trimmed down the size of this action and went from a triple sensor on the previous version of this action to a dual sensor here. However, any potential downgrade in sensitivity with the dual sensor has been mitigated by the inclusion of Casio’s new Smart Technology, making this an action capable of dynamic nuance.

The keytops are textured which provides a good amount of glide for your fingers and also happens to absorb moisture during longer playing sessions or during outdoor gigging in humid environments.

Overall, this is mechanically solid action, and there has been a very low incidence of action-related warranty claims during the first few years that this action has been on the market.

Piano Sound Engine

Casio’s Multi-Dimensional AiR Sound Source is the sound engine we’re working with here. On paper Casio appears to have brought back the same engine that was used in the PX-S3000, however, some of the marketing literature, as well as our own perceptions, seem to indicate that the sound engine has undergone an improvement.

The polyphony is the same at 192 notes, as is the total tone preset count at 700. Aside from the core Grand Piano tones, everything else sounds like it was ported right over from the PX-S3000 including the electric pianos, organs, synths, guitars, and various other musical instrument sounds.

The core grand piano sound however definitely sounds improved, and not just because of the speaker redesign either – it sounds like they’ve either added more sample layers to the tone or actually included a whole new sample altogether.

The amplifier power is the same at 16 watts, but there is definitely more clarity and depth to the sound than what the PX-S3000 was capable of.

‘Sound Mode’ has been brought back, and this offers the user a selection of editable reverb and chorus effects, along with a surround sound-like effect. The four Hall Simulator settings are present again, as are an array of DSP algorithms.

Connectivity

The PX-S3000 was solid in terms of input and output jacks, and the PX-S3100 is no different, making it a viable alternative to a legit stage piano.

To start, there are two headphone jacks, USB ports (type A and B) discreet 1/4” line outputs for when you need more power, a stereo mini jack line in, as well as inputs for a damper pedal, 3-pedal unit and an expression pedal.

There’s of course also an input for a traditional cabled power supply adaptor, as well as a slot for AA batteries if you’d like to power the S3100 cordlessly.

Courtesy of the complimentary Bluetooth adapter that also plugs into the S3100, you’ve also got Bluetooth Audio and MIDI here as well for connecting to iOS and Android devices. The S3000 oddly didn’t have Wireless MIDI, so we’re happy to see it’s been added here. The Chordana Play app is definitely one of the best remote control apps available so we would definitely recommend checking it out.

Notable Features

There are of course a number of highlights we could feature here, but we’ll focus on what really separates the PX-S3100 from its predecessor the PX-S3000, which is, of course, the new speaker design.

Despite no reported upgrade to the rated power output, this new speaker design is producing tangibly superior sound. The fact that Casio has pulled this off while keeping the weight down to just a hair over 25 lbs is a huge W.

  Conclusion

  Is the Casio PX-S3100 as groundbreaking as the PX-S3000 was? No, but it doesn’t have to be. Casio broke a lot of new ground with their first-generation PX-S series pianos when they hit the market in 2019. The PX-S3100 is simply the next logical step forward, and for anyone shopping for an affordable and absolutely loaded 88-key digital piano that can handle itself both at home and on the stage, the PX-S3100 is a very compelling option.
