Tested: Smart Piano vs. Standard - Full Keys, Light Up Keys… Plus rainbow tones! Last week, we set up the Smart Piano Keyboard with Speakers, eager to compare it to a standard acoustic piano. The first thing that struck us was the full-size, weighted keys with 256 tones and chord options—our fingers adjusted quickly, though the weighted feel does take some getting used to. The interactive music sheet and rainbow light keys on the keys were a pleasant surprise, offering a visual guide that helped us keep rhythm. We especially enjoyed the 256 tones and the MIDI controller capability, which seamlessly connected to our devices. The sustain pedal jack and audio input were convenient, as we tested it with our own demos. While the speakers are clear, we wish they were louder. Overall, the Smart Piano bridges the gap between traditional learning and modern tech, making it a versatile choice for beginners and intermediate players alike.
