Where to buy Musical Keyboards

Hi,
After tearing down a Roland E14-OR device, I was surprised how these beauties where built! the most difficult challenging part is the mechanical keypad, I wonder where it can be bought from china?

Note: every pin has a two carbon switches, with a little ramp between them, so the harder and faster you press the keys, it can measure the time between keypresses so it can act like a normal piano!


Do you happen to know a Chinese manufacturer where I can buy the keyboard?

A Modern MCU or a midrange FPGA can do the job.

Some more pictures

Why would you want to buy just the keyboard anyway?

If you are interested just in the keyboard part you can buy pure MIDI keyboards that don't make any sound, but just spit out the raw key presses via MIDI commands.

Although the "feel" is enormously variable. It certainly used to be possible to buy the mechanical part of a keyboard, it was a standard part of every "build your own electronic organ" project with lots of home-made contacts using gold-plated wire.

Doing a DIY project based on a ZYNQ maybe!

I understand exactly what the OP is asking about.

Back in the original days of keyboard synthesizers, a company called Pratt-Reed ruled the OEM keyboard world. Everyone bought their keyboard assemblies from them, and they'd sell you single units of anything they made. Want one of the inverse color white-on-black style, five octaves (60 keys), created for a specific customer? No problem! Just say "I want the keyboard from the Moog XYZ" or whatever and they'd happily ship you one. An absolute boon to those of us who toyed with homebrew synths back in the day.

Alas, Pratt-Reed is no more. And as someone else noted, everything is MIDI now. That's good in some ways, bad in others.
