I own a top flight acoustic piano and professional digital keyboards. I searched everywhere for a portable, super light-weight keyboard that I could carry on when flying/traveling to use for practicing and composition. The Casio CT-S1 fits the bill well, with a few very minor nits.

This keyboard weighs in at less than 10 lbs. yet is very well built and 'feels' sturdy and solid. It's physically impossible to have weighted or semi-weighted keys on a 10 pound instrument, but the key bed is otherwise very good. The keys are nearly full-size, have a matte finish and a good touch sensitive response.

The body of the keyboard is well constructed and does not feel fragile. The 'retro', minimalist look of the instrument with the cloth covered panel across the top is easy on the eyes. There is a built-in handle which allows carrying around your house or hotel with ease. It comes with a external power supply, but also runs on batteries. I sprung for a set of AA rechargeable batteries, worth the investment. Nit #1: You'll need to purchase a sustain pedal - not included.

There is a very good and wide range of sounds, most important of which are decent acoustic piano, electric piano and organ voices. A nice feature is a set of physical buttons and a volume knob across the front panel. There are dozens of additional sound and tone controls accessible via the function button and the piano keys. Nit #2: I would like to have dedicated buttons for the most used functions: transpose, octave shift and reverb.

The built-in speakers are very serviceable. There are 1/8" inch stereo IN and stereo OUT connectors, so I carry a couple of 1/8" stereo patch cables for connecting my Klipsch Groove bluetooth speaker (sounds great), tablets, phone, etc. The USB MIDI interface is ideal for for writing or transcribing music.

Nit #3: The Casio case for this instrument, when available, has an awkward design (load from the end ??), and has questionable padding for travel. Casio would do well to make available a decent, well fitting, padded case - even at half the cost of the keyboard, it would be worth it. I scoured the retail world for days to found a good quality, padded, but otherwise snug fitting case for airline carry on, but a case designed for this unit would be better.

This instrument is an excellent value.

Love tbe portability and unique design of this instrument. Has an expensive look to it. The sounds are amazing for this price range. I don’t miss weighted keys at all with this. The keys have a matte textured feel and they are touch sensitive. Lots of great hidden features on this keyboard. Tone layering, octave shifts, etc. If you want great sounds and aren’t wanting drum beats and accompaniment then this is a great instrument. I love that you can use batteries and take it anywhere. Played it in my backyard and my neighbors were coming out to listen!

Update: Loving this keyboard more and more as I delve into the full instruction manual (available on the casio website). I recommend printing for easy reference, as there are a lot of hidden features. I just discovered the hidden piano and organ tones, along with a piano/bass split. The organ tones are KILLER> if you love vintage sounding keys (wurly, rhodes, pipe, and gospel organs...even has a nod to vintage video game organ tones). My new favorite features are the simple record/loop feature where I can record one hand playing and then play the other hand over it. Super helpful for learning Bach pieces especially. This keyboard is exactly what I was looking for in that it has super impressive, high quality sounds/tones in an inexpensive keyboard. I love the styling on this. It is quite unique and premium looking with its fabric covered speakers. I think its great that it comes in 3 colors. I often find arranger keyboards a little cheezy and I really just want to play sheet music where I play my own accompaniament. The recorder feature allows me enough layering capability for my tastes, but if you prefer rhythms and arpeggiators I would go with the new Casiotone ct S500 or the cts1000v. Both of these are arranger keyboards and they have my attention currently, as they have the same updated soundchip but I still think the ct s1 has some sounds that are unique to it.

I used to use a cheap folding 88 key digital piano but it sounded bad; had a discordant metalic hum when playing middle keys. I had to give up on the idea of having a portal digital piano equivalent, they dont exist yet. Youtube videos did not do justice to the sound of this keyboard, in the best way. I will be using this for a long time I'm sure. Some additional notes: 1) The USB A port does not transmit MIDI out to my tablet via USB A to USB C cable. I'm ordering a micro USB to USB C cable to try the micro USB port for MIDI output and will update this reivew when it comes in; I'm hoping for both power and MIDI. 2) The USB A port on the keyboard does provide enough power to charge my tablet while I'm playing, which is very nice. 3) The frame is sturdy and rigid; it doesn't move under heavy chord playing. 3.5) The additional sounds (e.g., guitar, harpsichord, organs) make this keyboard one of the nicest at its price point, I just wish it had harps and the guitar didn't have that quiet synth sound in the background. 4) The key resistance is less than a normal piano but is enough to play notes in quick intervals, its actually a relief for my carpel tunnels, that and adjusting my seat height. 5) The handle is useful enough but would be better if it was a two direction cavity instead of one; I would not want to carry this more than a half mile using the handle, this is equipped take a guitar strap though. Overall, it has practically everything that I could reasonably ask for. I am very satisfied with this keyboard so far.

Update:
After using the Micro USB to USB C cable, I can confirm that the Micro USB port does provide MIDI output but does not provide power to my tablet when connected to that port.
