From pianissimo to fortissimo
Full of expression and joie de vivre: The AP-420 unites truly authentic piano sounds and exceptionally realistic keystroke behaviour with versatile modern features such as an SD card slot and line-out. With this extensive range of sound and functional options, the CELVIANO is perfect for players at any level.
The powerful new speaker system (2 x 20 watt) shows off the instrument's acoustic quality, while the elegant front consoles give it an eye-catching appeal.

16 AiF tones
The excellent AiF Sound source produces 16 top-quality tones, which truly come into their own in both classic piano repertoire and many other genres.

AiF Linear Morphing
The innovative AiF Sound Source technology produces top-quality tones perfectly suited to both classical piano music and other genres and enables gentle transitions between individual samples and dynamic levels. Complex stereo recordings from a top-quality concert piano (samples) with four dynamic levels provide a particularly authentic sound and allow you to play across various intermediate stages from piano to forte without any sound discolouration or audible leaps.

128-voice polyphony
Guarantee an absolutely first-class piano sound. The expansion of the range of voices has made interpreting complex works a true pleasure and lets you play sweeping chords and make extensive use of the damper pedal.

"Tri-Sensor" scaled hammer-action keyboard
Piano feeling: The scaled hammer-action keyboard with 88 touch response, weighted keys is based on the keyboard of a concert piano and provides an authentic playing experience. A third sensor in the keyboard allows players to use particularly fast techniques without the notes sounding unnaturally cut off.

Sequencer (recorder)
With the sequencer (2 track/1 song), you can record your own ideas quickly and easily in real-time (capacity: 5,000 notes).

Two piano setting keys
Piano sound tailored to your own taste: The piano setting key switches to grand piano sound at the touch of a button. Two settings are available: "classic" for a soft, discreet sound and "modern" with a more lighter, brighter character.

High-quality DSP effects
The AP-420 digitally reproduces the high-quality sound of a top concert grand piano complete with first-class reverb effects. The simulation of the resonating strings that is provided by the "Acoustic Resonance" CASIO effect rounds the sound experience off perfectly.

60 songs
Listen, sing along, play along: 60 top quality songs are stored on your AP-420.

8 digital effects
Live before an audience or at home in the living room: The sound diversity of your keyboard is enhanced by 4 reverb / 4 chorus effects.

88 Keys
The scaled hammer-action with 88 touch response weighted keys are based on the grand piano keyboard and make for an authentic playing feel.

Ivory touch keyboard
Both an audible and visual delight: The refined, matt keys with ivory touch not only look sophisticated and high quality, but provide a comfortable playing surface and additional stability to prevent your fingers from sliding. Enjoy a realistic playing experience!

Duet function
Ideal for lessons: the new duet functions allows teachers and pupils to play parallel to each other. The AP-420 can be divided into two keyboard areas, which can be transposed individually.

PANEL-Lock
Safe: With the PANEL-Lock function, the control panel is protected from unintentional moves while playing.

Metronome
Keep to the beat: The integrated metronome helps you keep to the rhythm.

2 headphone connections
Duet delight: two headphone connections are available.

3 pedals
The AP-420 features a 3-pedal unit with expanded damper capability.

Powerful speaker system
Impressive sound: The powerful two-way system with four speakers and 2 x 20 watts of output power ensures an exhilarating sound delivery. The sound is not only projected in the direction of the player but also to the rear or downwards, depending on the model.
This creates a three-dimensional and more natural sound.

SD card slot
The innovative SD memory medium offers a simple but limitless way to expand the internal song memory of the AP-420.

USB Plug & Play/Song expansion
The USB/MIDI connection enables further Midfile songs to be loaded into the internal memory via the "Song expansion". The memory capacity is 65 KB, enabling up to 1 song to be saved. No software installation from a CD-ROM required thanks to Plug & Play and the USB driver is compatible with both Mac and Windows (from Mac OSX and Windows XP/Vista).
