Compact and Innovative
With a depth of just 232 mm, it fits perfectly into any living room, bedroom, or studio space. Despite its compact size, it will surely fill the room with sound – the redesigned speaker system delivers excellent tone optimally and ensures stronger localization and presence. The Smart Scaled Hammer action is designed to guarantee a playing feel like an acoustic keyboard instrument despite its small size. Each of the 88 keys has its own weight and timing, enhancing authenticity.
Bluetooth Adapter
Enjoy the full range of the instrument thanks to the new Bluetooth Audio & MIDI adapter: select sounds, change settings in a flash, and play back songs from your phone or tablet.
Smart Scaled Hammer Action Keyboard
The hammer response simulation reproduces the key weight depending on position and playing speed – calculated individually for each of the 88 keys. It follows the physical differentiation: areas with different weightings.
Bluetooth
Easily accompany your favorite pieces: you can play music stored on your smartphone through the speakers of your CASIO PX-S1100 or PX-S3100. Play with different sound modes – for example, the surround effect for spatial sound experience.
Piano Bench
Steinmayer piano benches offer not only a high-quality look but also premium features such as stable legs with non-slip rubber feet, a smooth, precise spindle mechanism for height adjustment, and a durable, extra-large 55 x 32 cm comfortable seat covered in easy-care cord fabric. The cushion can be easily removed if needed. The solid wood construction ensures stable support and a load capacity of up to 120 kg.
Headphones
The KH-238 delivers full, balanced sound with rich bass and clear highs. It offers plenty of volume while maintaining clean and precise stereo imaging. The softly padded, wide headband is length-adjustable with 12 steps per side for optimal fit. For extra comfort, the ear cups rotate on two axes. The thick, soft padding of the circumaural ear cups also provides good external noise isolation. The integrated volume control on the cable is always within reach, making it easy to use with a PC or mp3 player. The 3.5 mm stereo jack plug ensures excellent transmission quality, and a 6.3 mm stereo adapter is also included.
Piano Course
Every beginning is easy – this motto also applies to the new edition of Michael Christoph’s piano course. If you’re worried that piano is too hard to learn, this course is a must. It introduces the instrument to beginners in a playful, relaxed way. Starting with familiar, simple melodies and progressing to two-handed playing of complete songs, it also imparts some theory knowledge along the way. Reading notes, rhythm, dynamics, and much more are covered alongside the exercises. The simple exercises guarantee quick learning success.

perfectly in small spaces. The Smart
Scaled Hammer Action keyboard feels
realistic feel and the sound is powerful and clear. The modern design rounds off the overall package. A clear recommendation!

But: the sound!! Doesn't work at all. With fast strokes, all right. But if a note is held just a little, you immediately notice the much too short sample . It sounds like a computer that gives an acoustic error message.
I fell for the marketing hype of Casio. My opinion: If you have ears, go for Yamaha or Kawai. In the same price range or if at all possible, 500 to 1000 euros more. By the way, I am a beginner without great demands.
