Casio Celviano AP-420 Review – The Look

It is said that beauty is in the eye of the beholder, but it’s hard to imagine anyone finding the AP420 Casio digital piano unattractive, thanks to the following.

With its beautiful brown (also available in black, as AP-420BK) wood-grain-like texture, the Casio AP-420 digital piano will fit right at home as part of your furniture, instead of sticking out like a sore thumb.

The Casio AP 420 comes with only a few buttons, without any LCD screen that detracts away from its elegant appearance.

Sturdy, height-adjustable bench matching the main cabinet.

Casio AP420 Review – The Sound

The Casio Celviano AP-420 boasts “four dynamic levels of stereo piano samples integrated with Casio’s proprietary Linear Morphing System”. What this gobbledygook means is that Casio has painstakingly tried to simulate the grand piano sound, and the result shows. The following are all simulated flawlessly in the Casio Celviano AP420.

  • large dynamic range you can expect from hitting keys at different velocities,
  • the decay effect of notes as you lift your fingers off the keys,
  • the sustain effect when you hit the pedals.

Casio AP 420 Review – The Touch

As far as feel goes, the Casio AP 420 digital piano does not disappoint. Let’s see why:

The “Tri-Sensor”, spring-less technology from Casio is the latest in its attempts to emulate the authentic touch of an acoustic piano.

The keys are weighted and feature “scaled hammer-action”, meaning keys on the lower scale feel heavier, while keys on the higher scale feel lighter, just as on a traditional piano.

The ivory touch of the keys, as opposed to the plastic feel of keys used on some even more expensive digital pianos, furthers the realism.

3 different adjustable sensitivity levels for touch response to match your playing style.

Casio Celviano AP-420 Digital Piano Review – Other features

Featuring just 16 different instrumental tones, it’s clear that the Casio AP420 digital piano is mainly focused on the basic piano sound and not on bells and whistles which would otherwise add on to the cost.

As can be expected from modern digital pianos, the Casio Celviano AP-420 comes with a built-in metronome.

The Casio AP420 Celviano is one of those “new-fangled” digital pianos that comes with a USB port only and no MIDI ports. To connect it to MIDI devices, you’ll need to get a USB-MIDI cable.

Record the tunes you play, and save out to an SD card or to PC through USB connection.

The Casio AP-420 Celviano digital piano comes with 60 preset songs.

Duet mode, and the ability to connect 2 headphones at once, allows student to learn easily from a teacher.

Casio Celviano AP-420 Digital Piano Review – What others say

Take a look at some testimonials from satisfied owners of the Casio Celviano AP-420 digital piano:

“…The sound quality through headphones is really authentic (you can even hear a partial overtone series if you listen carefully on sustained notes–which must be from how they captured the tones since obviously there are no strings to resonate) and the touch is fantastic–it’s definitely not too heavy or hard and actually feels surprisingly similar to an authentic acoustic piano…

“…The keys have a pleasant, non-plastic feel, and are nicely weighted. I immediately loved the touch and tone of the piano. If you’re looking for a nice interim instrument to keep you occupied after you outgrow your small keyboard and before you drop a few thousand on an acoustic piano–this is it. It has all the features of a “real” piano–pedals, hammer-weight keys–and will allow you to expand and refine your skills before moving on to a regular piano…

Casio Celviano AP-420 Digital Piano Review – Bottomline

Casio has certainly outdone themselves. The Casio AP 420 Celviano digital piano is a fantastic product. It matches the features of many digital pianos in the higher price range ($2000+) for less than half their price! If you’re looking for realistic piano sound and feel in a beautiful package, look no further than the Casio Celviano AP420.
