Casio 61-Key Portable Keyboard CT-S1BK Bundle - Bluetooth MIDI Audio

In this review of the Casio 61-Key Portable Keyboard (CT-S1BK) bundle, the bottom line is simple: this keyboard is an excellent choice for beginners and intermediate players who want a portable, well-built instrument with modern connectivity. The single biggest reason to buy is the combination of 61 full-size touch response keys and the wireless Bluetooth MIDI/audio adapter, which together make practicing, composing, and playing with mobile apps or a laptop effortless. Sound quality from the built-in speakers and the variety of tones make it a practical, everyday instrument.

Key Features

• 61 full-size touch response keys: Provide expressive dynamics for beginners and more experienced players who want gradual velocity response while practicing or performing.
• 60 AiX powered tones: Deliver realistic instrument voices including a stereo grand piano sound that works well for practice and small performances.
• Powerful bass reflex speakers: Offer a surround-like effect and clear low end so the keyboard sounds fuller than typical portable models.
• Class compliant USB-MIDI: Connects to the Chordana Play app and DAWs without drivers for a quick setup with phones, tablets, or computers.
• Wireless Bluetooth MIDI/audio adapter: The included WU-BT10 enables untethered MIDI and audio streaming for mobile practice and app integration.
