Sourcing Pressure Sensitive Buttons/Pads

I have a Big Project^tm in my head, but first I’d like to start with a smaller prototype.

It requires some pressure sensitive buttons/pads - like the kind you might find on an MPC or a Push.

I have found a way to DIY them: Reddit - Dive into anything

However, I want some that are a bit more professional, with a rubber key cap, and I need 64 of them.

Does anybody have any idea where to source something like that? I’ve tried typing all the combinations I can think of into AliExpress, but I just get crap results. I’m sure there are some in there, but I can’t find any.

Also, any discussion on nice rubber pads. I can make this project work with just nice pads that aren’t pressure sensitive, but pressure sensitivity kicks it up a notch.
