Casio AP-250 Celviano features 18 built-in tones, 60 pre-recorded songs, 128 notes of polyphony, reverb and chorus. It also supports USB integration with Windows or Macintosh computers. The highlight of the piano is its four-layered stereo sound reproduction of a grand piano. Built into the keys is a scaled hammer action based off of spring-less sensors. This gives the piano a rich, authentic sound capable of nuanced and expressive performances. The sounds are integrated with Casio’s Linear Morphing System, guaranteeing improved dynamics and seamless transitions.
A high range of supported polyphonic notes guarantees a clear performance, even when demanding passages and extensive use of damper pedals are required. The pedals are additionally supported by further innovation on the part of Casio: Acoustic and intelligent Resonator (AiR) technology. This technology provides damper resonance, which enhances the sound of the sustain pedal by emulating the dampers lifting off the strings.
The AP250 is ideal for piano students – the 60 pre-programmed songs can be played at any tempo, which is especially helpful for beginning and intermediate players. The player can practice using the internal speakers or they can plug in their headphones, ensuring that no one else is distracted by the noise. The piano also comes with a “duet mode,” allowing for simultaneous play by both teacher and student. Included also is a score book, allowing students to read the music as they play, speeding up the learning process.
USB support means that the digital piano can be connected with any supported operating system. No device driver installation is necessary. Though a fairly rudimentary feature in modern electric pianos, this is nevertheless an indispensable feature for transposing, composing, or recording music from the keyboard to music software programs on the computer. Anyone familiar with music recording using GarageBand, LogicPro, MixCraft, Finale, or any other music composition/recording software knows firsthand that programming or transposing piano music is easily the most tedious aspect of music composition. With appropriate software installed, USB adaptability removes the tedious work required to capture performances or sheet music.
This is a professional-grade digital piano, but it would not be suitable for large arenas or outdoor concerts. It is intended for in-home use, and its features are optimized for this venue. In a café or small music venue, the piano would probably be adequate; connected to additional PA systems, some of the quality would be lost. For most users, this will not be a complaint.
The piano is heavy. It ships at over 125 pounds, and when set up, it weighs almost 90 pounds. It ships with a piano bench and is finished with an attractive oak brown color. The sound and quality is highly comparable to more expensive digital pianos, and it comes with many features. It makes an excellent introductory piano, particularly for those who are learning the instrument, or as an intermediary piano for those who are still saving for an acoustic model.
