Exceptional sounds, action, build quality and portability
Basically a brilliant and highly portable piano/keyboard from Casio. Superb range of sounds and a lovely fluid action, plus great vintage looks and solid build quality. The only neg is a less than intuitive set of buttons, which hides away many of the CT’s useful features and sounds. A tiny bit quiet too, but fine for everyday use. Casio, please put the headphone jack up front and make the instrument buttons toggle thru. Beautiful job though, I bought two, red and white! Lightweight enough to rest on your lap whilst playing. Works well with a plug in pedal. There’s also a longer and louder 76 key version, and optional bluetooth add on.

Awesome Keyboard, Super Fun to Play
I got this as my first keyboard, and I’m seriously impressed! The sound is amazing for the price and has really nice piano tones, plus some cool vintage electric pianos and organs. The keys feel great too, full-size and responsive. It’s lightweight and super easy to carry around, which is perfect if you want to move it from room to room or take it somewhere. I love that it can run on batteries, so I don’t always have to plug it in. The controls are simple and easy to use, no messing around with complicated settings. For the price, this is an awesome keyboard, whether you’re just starting out or need something portable and fun. Definitely worth it!

Sweet spot on price and performance, and not only for a beginner
I got the black one, and I will say that the text next to the buttons is more grey than white. This worried me for a few hours; I wondered if the red one with black text might have been easier to see. But never fear: after just a few hours you realise that it's so easy to use you don't need to be able to read the text, you don't even need to be able to see that buttons. You can select all the sounds by touch in the dark :) You may find that the 28 default sounds (I'm not including the change any use of 'surround' makes) it comes with enough for you, as they are all very useable. There are 61 tones in total if you want to experiment with keyboard selection. There are 7 more you can add to the top buttons for easy access too; layers octave shifts, reverbs, pedal function (doesn't come with one) etc. can be fiddled with and saved to the instant access top buttons. If you want to add those 7 user configs, or really do pretty anything else you'll need the manual. But you'll remember how to change the metronome tempo, volume and time signature easily enough. You can set other things to be recalled when you switch it on too., so you don't need the manual often once you have the instrument set up how you like it. So great sounds, a players interface, usb to your pc if you want to use Ableton or Cakewalk etc. One thing annoys me: the manual says that I need to change the battery type from normal if I use rechargeable batteries. I do not need to do this on my Roland, so why should Casio insist that I do it here?

Overall - Really Good
This is a quality keyboard - which I’ve used through a mixer and effects pedals. However, keys are just a tad smaller than standard and I find a little slippery

Casio CT-S1 Portable Piano keyboard Black
Useful and handy while operates on battery, fairly light to carry wherever the locations which I could not carry my Casio 88 key e.g walk on uncomfortable pathways, up and down steps etc. The Piano sound is Good , Cathedral Organ sounds good, easy to select the sounds, so far so good..

FANTASTIC! CASIOTONE CT-S1
I have just recieved my Casio CT-S1 keyboard today and it's (pardon the language) bloody fantastic! The onboard speakers are incredible! I doubt that I would want to use any external speakers when taking it out, but if opportunity arises, using external speakers would only enhance an otherwise amazing sound even more! I HAVE BEEN PLAYING ALL AFTERNOON, and emjoyed it so much, I actually forgot to eat :) I am one of the fussiest people going when it comes to sound quality and quality of instrumental sounds.....this simply blew me away!! so anyone sitting on the fence (like I did, I have to confess) don't hesitate if looking for a great sounding portable keyboard, at a fantastic price. I have a Yamaha Genos as my main Workstation for composing at home, so as you can imagine my standards are very high. Just wanted this to take out with me when I perform. Honestly I cannot wait to take this out with me! YouTube videos do not do the sound of the onboard speakers any justice, you wold have to hear this for yourself to believe how great this little keyboard is. Anyone reading this, please bear in mind that to get the best sound from this you should have it on a stand, as there are speakers on the underside as well which many people don't realise, so you don't want to mute those by putting it on a table if you can possible help it. Apart from my Genos, this is the best buy I have made in a while. If there had been a 10 star option on Amazon it would have got a 10 for sure.

Plays and sounds Great
Plays and sounds great , but I think maybe I should have gone with the 76 key version I find it just a little small for me on some songs , you can octave shift of course .. but love the sound quality of the instruments.

Why did you pick this product vs others?: It is a great keyboard with minimal features, that help in learning to play. As someone who wants to learn the skill, I did not want a lot of accompaniment styles and on board song banks, which I think is a dead payload, IMHO. This keyboard has great keys, with a nice texture that do not feel "plasticky". The keys feel real good. Features: Minimal features, that help you learn the skill of playing, and also get you to play the keyboard without a lot of distraction of fancy features. Quality: The keys have a great feel and do not make a residual plastic noise. They respond well to the touch. Music selection: The patches sound great. the piano patches have great variations and great sound. The sound is bright, warm, full and rich.

Llevaba un tiempo buscando un teclado secundario y portable para llevar conmigo cuando estoy de viaje y matar el gusanillo de tocar un poco. Ya sé que no es lo mismo que un piano "de verdad", pero no puedo llevarme mi piano acústico en el coche. He probado de todo: el P45 de Yamaha, el Privia de Casio, un teclado plegable de una marca que no mencionaré... Los primeros son pianos eléctricos más que decentes, pero demasiado voluminosos y pesados como para transportarlos con facilidad. En cuanto al teclado plegable... Uf... Digamos que se trata de una excelente idea pésimamente ejecutada, con un tacto penoso y un sonido aún peor (¿para cuándo un teclado plegable decente de una marca reconocida?). Una verdadera lástima, porque era comodísimo de transportar y, una vez desplegado, tenías un teclado de tamaño completo a tu disposición. Este nuevo Casiotone suena verdaderamente bien, como un Privia. Los altavoces proporcionan un sonido decente incluso a tope de volumen. El aspecto es robusto. El plástico de las teclas está levemente texturizado y es agradable, aunque esto irá en gustos, claro. El teclado en sí no es contrapesado, es decir, no tiene en absoluto el tacto de un piano acústico ni el de un buen piano eléctrico, pero ofrece cierta resistencia y tiene una buena sensibilidad. En la parte negativa: que solo tiene 61 teclas, claro. Se queda pequeño para interpretar muchas piezas, pero los teclados similares de 88 teclas son realmente enormes para un maletero convencional (me repito: ¡¿para cuándo un teclado plegable decente?!). Lo recomendaría para aquellas personas que quieren un teclado secundario fácil de transportar para viajar con él o para tocar en cualquier sitio fuera de casa. Para los principiantes puede servir para dar los primeros pasos sin un gran desembolso, pero durante muy poco tiempo: si continúas tocando el piano vas a necesitar un teclado completamente contrapesado donde la dureza y el tacto de las teclas sea más realista que en el Casiotone o en cualquier otro teclado de esta gama.
