Baby grands £4505, minimum order two. Entirely easy to find and Chinese suppliers are delightfully optimistic about shipping them half way round the World, the real issue is whether you're happy putting that amount of money on the table for something that you've not seen from a supplier who might not be entirely accurate when responding to your questions.

It will be cheaper then buying all the keys.

That approach is much more hassle than it's worth. All the electronics, i.e. both chips and contacts, is likely to be on the same board, with no real demarcation between the subsystems. I've said it before: get something like a (second-hand) M-Audio keyboard which is strictly an input device with accessible MIDI.

(That's actually about the rate that I play piano.)

What?
2500 notes per second ?

Erm, you made me recheck my numbers, I don't know what I was thinking.
I can do the 128 notes in under 16-20 milliseconds.
That's 6400 to 8000 notes per second.
128 notes/(22.731081seconds-22.714545seconds) = 7750 notes/second

I'm thinking of a first prototype and then maybe build a batch of 100-500 units, so I think I should definitely find something in china, cause I want to make a kickstarter campaign.

Reasonable. Try Ali (i.e. specifically /not/ AliExpress etc.).
