1. Lack of Authenticity: One of the most significant disadvantages of digital pianos is the lack of authenticity when compared to acoustic pianos. The tactile sensation of keys on a digital piano is often simulated, and the sound is amplified electronically, which can result in a less rich and resonant sound.
2. No Sonic Improvement Over Time: An acoustic piano’s sound improves over time. As the strings age and the hammer felt gets compacted, the tonal quality changes and typically improves. However, a digital piano will always sound the same because it isn’t an acoustic instrument.
3. No Miking-up: Unlike acoustic pianos, digital pianos cannot be “miked up” for performances, meaning they cannot be connected to a microphone and then to a PA system to amplify the sound. This limits their use in larger venues or recordings.
