Encoding problems in the video

Thanks Simone, I hadn't noticed it. Can you believe I haven't learned how to edit audio + video yet? I use Virtual Dub but it's really annoying me...

Adobe Premiere... Simple and intuitive.

Thanks Simon, you are providential!

Here is the updated version. I'll also update the link above, okay? I haven't cut anything from the video. Everything just as my mother made me.

Eeee even so! And what did I do?

Rather, the sounds seem the same to me as my P95. The piano is truly electric; I don't like it, just as I don't like it on mine.

I don't think I'll ever buy a Yamaha again. Playing it every day, in the end, your ear gets used to it. The sound attack isn't too bad if treated with a bit of reverb; it's everything else that sounds truly electronic. What do you say, Enrì?

Bravo Foster, you play well! I like your style. Regarding the keyboard, I agree with Simon, the sound is very fake.

Thanks for the opinions.

What I can say is that for a 590 euro keyboard, it sounds (and works) better than some properly tuned pianos.

It's light enough to carry around (11kg).

The sound is decent on a stand, where the highs and lows are heard very well. Placing it on a table, the sound does not meet expectations (this fact is mentioned in the manual anyway).

Underneath the P105, there are indeed 2 speakers.

As for the difference with the P95, which I have NOT tried, YAMAHA shows this diagram on their website.

Mixed like that, it doesn't say anything. It isn't even clear if such improvements (P105 red line, P95 blue line) are actually perceptible to the human ear.

(they look like diagrams used to convince you to buy diet pills)

While the difference in sound between the P105b and my P60 from 2002 (purchase year 2005) is overwhelming. (at the time it cost around 1200 if I'm not mistaken).

Another thing:

with the Kawai MP6 and MP10, the harder I press the key, the louder the sound becomes. It doesn't seem to have a maximum limit.

With the P105, there is a maximum limit. Although you can adjust the touch slightly with 4 different settings.

This scene came to mind regarding this ... a review of my "video review"

Well, Kawai pianos really have a different system and use sampled sounds. In reality, the limit exists, but by making very good use of samples, pressing the key with more force corresponds, as in an acoustic piano, to greater kinetic energy of the hammer which ensures that, once the string is struck, more partials develop -> hence the change in timbre (timbre characteristics are influenced ONLY AND SOLELY BY THE PARTIALS; in physical terms... not by amplitude, not by phase, not by frequency... whereas in psychoacoustic terms... not by volume, not by pitch...). Our ears have become accustomed to this change in timbre; it would sound unnatural to us if pressing a key softly or loudly only changed the volume.

Like you, I also think (and you made this very clear) that that graph gives me no indication unless reference values are provided. This frequency response diagram could mean a lot or very little. An increase in dB SPL at low and high frequencies (here we are talking about sound pressure level), okay, by how much? At which frequencies? It doesn't give me much more information than what I would have obtained when buying a Bontempi keyboard for my cousin when she was 5 years old, and for a company like Yamaha, I think this is unacceptable.

The fact that there are two speakers under the keyboard is related to the production of low frequencies. If we imagine a three-dimensional room and our sound as a ball (the sound must be stereo), the volume of the sound decides whether the ball should be placed further forward or further back relative to my observation point, the pan decides if it should be more to the right or more to the left, and the frequency decides if it should be higher or lower. It is no coincidence that in live setups, the subwoofer chain is placed on the ground while the line arrays are placed high up. This reflects the intrinsic spatiality of sound.

I didn't quite understand this thing about the three-dimensional chamber. Could you explain yourself better, Simone?

I'll try with some models, then you can tell me if it sounds clear this way...

Psychoacoustic sensations of sound allow us to perceive it in three dimensions. In particular: frequency (high note -> high frequency value, or low note -> small frequency value) determines the pitch of the sound. The term "pitch" (altezza del suono) was not chosen by chance, precisely because our ear places the sound higher if the frequency is high, and lower if the frequency is low; in fact, if you think about it, pitch is the first parameter we notice, the best parameter recognizable by the ear in terms of sensitivity, and even if we ask a child what music is, they will answer with musical notes which, in their limited view, are pitches. In an x,y,z space with x and y as plane axes and z as height, we have precisely defined z with the pitch of sounds. The y-axis, instead, allows us to identify which side the sounds are on: left or right. Lastly, on the x-axis, we find volume, which in this case of spatiality I prefer to call the sound plane. The combination of these three quantities gives us the mental representation of sound in space. As I believe I mentioned in another post, it is no coincidence that line arrays are placed high up on the left and right and the subs on the ground. We try to accommodate what our ear would want to hear, which is an extremely sensitive and fascinating organ. In studying it through psychoacoustics, I was literally fascinated—I can find no other term—in discovering its anatomical behavior.

Returning to us, here below are some examples:

Which represents our placement of frequencies relative to the z-axis.

Which represents the position of the signal relative to the y-axis: further right or further left.

Volume expressed on the x-axis.

I hope everything is clearer now.

I am attaching another test: "Over the rainbow".

Since everyone is murdering it, pigs and dogs, amateur singers and the like, I will add myself to the list too.
