Casio vs MUSTAR Key Specs
Key Action
The Casio Casiotone CT-S1 features touch-responsive keys that allow for dynamic control over volume and tone based on how hard you strike them. This is essential for expressive playing. The MUSTAR 61-Key Lighted Keyboard does not specify its key action in the provided data. Without explicit mention of touch sensitivity, it is unclear if the keys offer the same level of dynamic response. For players who need to control nuance, the Casio’s stated touch-responsive mechanism is the safer choice, while the MUSTAR’s action remains undefined.
Sound Engine
Casio uses its AiX Sound Source technology to generate tones. This engine aims to provide realistic and expressive sounds, ranging from grand pianos to vintage synths. MUSTAR employs a DREAM source for its audio generation. While both brands aim for quality, the AiX source is a specific proprietary technology from Casio known for high fidelity. The MUSTAR’s DREAM source is less commonly detailed in technical comparisons. If sound realism and advanced synthesis are priorities, the Casio’s AiX engine offers a more recognized standard for portable keyboards.
Learning Features
MUSTAR includes lighted keys and three intelligent teaching modes: One Key, Follow, and Ensemble. These features are designed to help beginners, especially children, learn songs quickly by following the lights. Casio does not list lighted keys or specific guided learning modes in its data. Instead, it offers a metronome and a built-in guide for exploring deeper features like EQ and virtual venues. For absolute beginners who need visual guidance, the MUSTAR’s lighted key system is a significant advantage.
Included Accessories
The MUSTAR kit is comprehensive, including a music rest, sustain pedal, piano stand, headphones, microphone, power adapter, and USB OTG cables. This all-in-one approach means you have everything needed to start playing immediately. Casio lists only the keyboard itself in the product data, with optional battery power and a strap. You would need to purchase accessories separately for the Casio. If you want a complete package without extra shopping, the MUSTAR provides far more value in included hardware.
Connectivity
Both keyboards support USB-MIDI connectivity, allowing you to connect to computers or smartphones for teaching apps and music software. Casio also offers optional Bluetooth connectivity with an adapter, enabling wireless streaming and app usage without drivers. MUSTAR mentions USB MIDI and app compatibility but does not explicitly list Bluetooth support. If you prefer wireless connections for modern apps and streaming, the Casio’s optional Bluetooth feature provides greater flexibility and convenience.
Which Casio or MUSTAR Keyboard Fits You
Portable player seeking high-quality sound
The Casio CT-S1 uses AiX Sound Source for dynamic tones. Its bass-reflex stereo speakers and Surround mode create immersive audio. Weighing only 9.92 pounds, it fits easily in a bag.

Beginner needing guided learning tools
The MUSTAR keyboard includes lighted keys and three teaching modes to help you learn quickly. It offers 600 tones, 500 rhythms, and 65 demo songs.

User wanting built-in accessories and controls
MUSTAR includes a stand, pedal, headphone, and microphone in the box. It features a joystick for real-time control and dual voice modes to combine sounds. You can split the keyboard for two players.
