text: Most immediately noticeable with Casio’s new CDP-S digital pianos are their diminutive size and portability, but know they are crammed with excellent features. Both of these sleek instruments weigh less than 25 pounds each and have a realistic piano sound and an excellent weighted hammer action keyboard with 88 full-size keys and simulated ebony and ivory featured keys.
  They are powered by an included small power supply or by six AA batteries; they also come with a stereo speaker system plus a headphone output jack for quiet practice. More experienced pianists may replace the included sustain pedal with Casio’s SP-34 three-pedal portable model and there are the optional CS-46P wooden stand and SC-800 carrying case available.
  Both models have bright backlit LCD displays, a trio of MIDI jacks, a USB port that will work with Macs or PCs—even your Android or iOS devices with no driver needed. Super fun is the free Chordana Play For Piano for iOS/Android App. You can easily customize the keyboards, learn new MIDI songs, playback audio files with pitch/ tempo control and view PDF scores.
  The CDP-S150 includes a stereo grand piano plus nine other tones, adjustable effects and temperament and a one-button recorder. It sells for $479.99 MSRP. The CDP-S350 at $549.99 MSRP has 700 sounds, 200 accompaniment rhythms, a pitch-bend wheel, a six-track MIDI recorder with USB storage, and convenient “Registration” buttons to save/recall sounds and settings.
