Now that we’ve seen the quick differences, it’s time to finally go into the details. Let’s have a look at the detailed comparison of different features between William Allegro 2 and Yamaha P45-


William Allegro 2 has surpassed its predecessors in terms of look and design. Its new look is both attractive and professional. Plus, it’s added with a matte black finish! Allegro 2 has made its way out of the unergonomic title given to its predecessors.

Speaking of its design details, it has a front panel that compromises the main components. They are the volume knob, 6 buttons to control the 10 sound types, metronome, transpose, LCD display, Octave/function options, transpose, and the record mode options.

On the contrary, Yamaha P45 comes in a rather bland look than the William Allegro 2. It can be found in 2 classic colors, black and white. It also has a matte finish to it like Allegro 2. 

It has basically 3 buttons on the front panel. They are the Power button, Volume button, and the Grand piano function button. Its body is made up of plastic. 

So as you can see, the Williams Allegro has a more versatile and robust look than Yamaha P45. 

And the design also allows both the pianos to keep their lid closed or open.

Many of you keep the design as the top priority while choosing. There’s a lack of color availability in pianos that many want. Another scenario is when people are more into simpler looks. 

So here’s our recommendation for digital pianos with designs you might like-


Usability is quite an important factor that impacts the buying behavior of many.

So let’s get straight to the point. Yamaha P45 is much more complicated to use in terms of switching modes and stuff like that. For instance, you have to hold the grand piano button and the E3 key to start Metronome in Yamaha P45. 

But, you can just do it through the Metronome button present in William Allegro 2.

There are buttons assigned for each of the tasks you need to perform on William Allegro 2. For instance, there are record, play, voice settings, transpose, octave, function, reset, split, reverb, and other buttons assigned for settings like these. 

But as we’ve mentioned before, in P45 you need to press a unique key added with the grand piano key for each setting. You need to find it in the manual.

So if you are a person who needs a button for everything, William Allegro 2 is the way to go! But if you want a compact and basic-looking piano with limited buttons, you can go with Yamaha P45.

Sound Quality

Speaking of the sound quality, both of these pianos offer a basic sound quality which is okayish looking at their price range.

However, users are mostly seen to complain about the Yamaha P45’s sound quality. It’s just the fact that the speakers produce basic sounds. So, if you are looking to play regularly on a big platform you might be unsatisfied.

But what’s good here is that the stereo sound of P45 is recorded from an acoustic Yamaha piano played in a full concert. Plus, it uses the AWM advanced tone generation. It’s a sound generation system developed by Yamaha. It mimics the tones of a real acoustic instrument and offers tone shaping via modulation, filters, etc. 

And unlike a real acoustic piano, the sound quality of these digital pianos don’t depend on open or closed piano lids.

William Allegro 2, on the other hand, lacks premium sound quality. But keep in mind that the price is very low. Plus, users seem to be satisfied with the sound produced from the 2 front-firing speakers looking at its price point.

So, in the case of sound quality and tone generation, Yamaha p45 is the winner. It has a much more realistic sound to it compared to Williams Allegro 2. Also, you can always use external DACs to improve your sound quality. The concern here will be whether DACs are beneficiary or not.

But here’s the thing. If you are already investing in your music career, why not invest for the long term? If you could spend a couple of hundred dollars more, you can get an even better tone and sound. These tones would be even more like real acoustic pianos. 

Here’s our recommendation for such pianos-


Talking about keys, both of these digital pianos have a full set of 88 hammer-action weighted keys. This means that you’ll get to play all 7 octaves of notes by them.

Weighted keys give you the feeling of playing an acoustic piano. But the weighted keys of William Allegro 2 have some limitations which Yamaha P45 doesn’t. For instance, the keys don’t feel that much hammer weighted in William Allegro 2 like those in Yamaha p45.

So in terms of the quality of hammer-weighted keys, P45 is the winner. Many users on twitter are raving about the Yamaha p45 piano.

Plus, William Allegro 2 has weighted keys surely, but they are not graded. This means that all keys feel the same here.

But in the case of P45, they have Yamaha’s GHS (graded hammer system) included. So the keys are weighted plus graded. So when you move from bass to treble notes, the weight of the key changes. 

So it gives you more of an acoustic feel while playing Yamaha P45 than the William Allegro 2! 


The effects present in the William Allegro 2 are reverb, chorus, and modulation effects. In addition, there is a MODFX feature that allows the rotary speaker effect and vibrato effect in a digital piano

In the case of Yamaha p45, there’re also reverb and chorus effects like Allegro 2. But the modulation effect is absent here. 

However, there are 4 types of reverb effects in p45 which are Room, Hall 1, Hall 2, and Stage. These reverb effects are in order towards a high acoustics feeling.

Now, there are 10 piano sounds present in both William Allegro 2 and Yamaha P45. In the William Allegro 2. They are grand piano, organs, strings, electric piano, basses, and synthesizers. 

And in Yamaha P45, these sounds are grand piano, electric piano, pipe organs, harpsichords, string section, and a vibraphone patch. Plus, you can add any of the 4 reverb effects on either of these sounds.

Thus, you get more of a variation in the reverb effects in Yamaha P45 than the William Allegro 2. On the contrary, you get almost similar effects and sounds on a much cheaper William Allegro 2.
