The Casio CT-X3000 features the new AiX Sound Source developed from their range of digital pianos. The sounds produced are of a high standard with powerful bass notes through to clear high notes. Sounds are faithfully reproduced from acoustic instruments with sensitive treatment of the notes resonance. Using the high-performance Digital Signal Processor (DSP) numerous algorithms are used to suit the expressiveness of the performer. Powerful sounds are produced from the two 6W speakers whether at home or at a performance venue. The red detailing on the speaker certainly makes this keyboard stand out.
