Respect for such a challenge and huge amount of work and bravery!

(Some time ago i was thinking to do similar thing with my Modx Yamaha, to make a sound module from 76 keys) light small portable.

Excellent skill there - beautiful work!

In the end it is a matter of trust and endurance.
I always like these modifications!

Wow, all Kudos to you man!
I can see more clearly now, lot of competitions in this forum!

PianoLuminescent, that’s one awesome mod! Nerves of steel, too.

You mentioned reducing the weight… have you put it on a scale, to note the weight difference?

And I presume the final size was some multiple of the key sensors, which are grouped together? You just removed the outer modules?

Yes, I cut down the 88 keys to 61 keys. With a dremel cutting discs, I cut down the keybed metal frame and keys contacts board.
And use a electric Jig Saw to cut the piano exterior frame.

Didn't you also have to resolder some circuit tracks on the key contacts board, after cutting?

I can see, I have an experience guy here. Well you are right, the first board I cut, I cut to much!, so I have to resolder one resistor line. The rest was a piece of cake.

They are 3 Key sensors Board connect together, so I have to cut the left and the right boards.

88 Keys Weights: 40.1 Lbs (18.5 kg)
61 Keys Weights: 31 Lbs (14.1kg)

88 Keys Dimension: 50.7" (128.7 cm)
61 Keys Dimension: 35.8" (91 cm)

Fabulous project what an excellent piece of work.

I’m actually on my way to check out his keyboard. If all is in working condition, I’m buying it today!

So here is the story. I own a Nord Piano 2 and enjoyed it however unable to upgrade to White Grand and the Soft Piano sounds that came out 2023-2024 because the OS is too old. Then I found this Nord Piano 4 with 61 keys. I reached out to Pierre and made the appointment to see his piano 4. On that day I was searching for a Notd Piano 4 61 keys but came up empty. I was curious why it was so cheap? Only the 88 key version existed. Then found this forum! I was so impressed with Pierre’s work of cutting a 88 key to a 61, I bought it off him and in the process of setting up. It was meant to be. Now I use it as a slave to play with upgraded new piano sounds. More to come! Stay tuned.
