The Casio CT S1 is also a portable keyboard with 61 touch-sensitive keys, but it offers more features and functions than the NP 12. It has 61 tones and a variety of effects and features, such as arpeggiators, auto-accompaniment, and a pitch bend wheel. It also has a USB port for connecting to a computer, allowing for MIDI connectivity and access to music software. The CT S1 is designed for musicians who want a more versatile keyboard for practicing, performing, and recording, with a wider range of sounds and functions.

Design and Build Quality

The Yamaha NP 12 has a sleek and compact design, which makes it easy to carry around. It weighs only 9 pounds and is only 40 inches long. On the other hand, the Casio CT S1 is slightly heavier at 10 pounds but more compact at 36.6 inches. However, it has a unique design that is reminiscent of classic analog synths, which may appeal to some users. In terms of build quality, both keyboards are well-built and sturdy. The Yamaha NP 12 has a matte finish that gives it a premium feel, while the Casio CT S1 is also available in red finish for a more eye-catching appearance.

Key Action

The key action is an essential factor to consider when choosing a keyboard, as it affects the overall playing experience. The Yamaha NP 12 has a piano-style keyboard, which mimics the look of an acoustic piano. The keys are not weighted, but they have a nice bounce to them and touch-sensitive that makes playing enjoyable.

The Casio CT S1, on the other hand, has a similar key action from Casio, not weighted but is adjustable in sensitivity. This means that the lower and higher keys are the same and relatively easy to play for most people. Overall, these keyboards are very similar with unweighted keys and are light enough to play with all the built-in tones.

Sound Quality

The sound quality is arguably the most crucial aspect of any keyboard. The Yamaha NP 12 features Advanced Wave Memory (AWM) sampling, which captures the sound of an acoustic piano and reproduces it digitally. The result is a rich and authentic sound that is hard to beat. Unfortunately, you only have 10 tones on this keyboard.

The Casio CT S1, on the other hand, has an AiR Sound Source, which uses a multi-dimensional morphing technology to create a dynamic and expressive sound. The keyboard also has 61 built-in tones, which makes it a versatile option for different types of music. Overall, both keyboards offer excellent sound quality, but the Casio CT S1 has a wider collection to fit different music styles and preferences. Read also: Yamaha NP 12 Vs Yamaha P45.
