I recall reading a question on a music forum (not sure if it was this one) where someone asked why a keyboard like the Triton or Motif weighs so much more than, say a Yamaha PSR keyboard.
One of the responses was: "they put weights in pro keyboards." Is this just nonsense, or true? I mean.....lugging my heavy synths around is becoming a chore, and, if this is true, are those weights removable?
really, my m3-73 weights 17 kg, while the m3-m is less then 5 kg
that means the keybed weights 12 kg and guess what? it's hollow with no bottom, a metal frame + the keys
if anything is attached there, it's somewhere in the keys... I don't think they'd do that

Yes, that's true. But my M3-61 has a plastic chassis, and it's a lot heavier than I expected.
But....my heaviest synth is a Kurzweil K2661. Now I know the chassis is metal, but it has to have something inside to give it all that weight! Even the power supply can't be that heavy.
Actually a good bit of the weight comes from the power converter. Most high end keyboards have the converter built in so that there is no confusion when plugging in the power cable which can lead to a blown board if you plug in the wrong type. Cheaper keyboards use wall warts which some can be quite heavy...but can be confusing. I blew my old Korg Poly 800 because I plugged in an 18v box when it only wanted 12v.
Also there is much more processing being done in higher end keyboards, so you find heat sinks on the processors...something you do NOT find in lower end all-in-one machines.
Also as mentioned, the chassis is made of steel or some other heavy metal...mostly to endure years of road service. I have also found primarily in Korg that each of the outputs are reinforced and sometimes encased for their protection. As you add all of this up together you can add 10-15 lbs in just extras to make the keyboard sturdy.
In an effort to reduce carbon emissions from the manufacturing process of plastic and other light-weight materials for keyboard assembly, all companies are now replacing environmentally unfriendly components with solid granite.
My Triton Studio as well as my Triton Extreme have waits! But they are labeled "Pause" on both of them. I don't see how taking them out would make the board any lighter?!
