Looking for instrument name

Hey everyone,

I recently saw a TikTok of someone playing a really unusual electronic instrument and I’m trying to figure out what it’s called. It looked like two flat boards/layers stacked on top of each other, with a layout similar to piano keys (kind of white/black pattern), but they weren’t actual keys, more like touch-sensitive surfaces.

When the player pressed down, the whole surface seemed to physically move down quite a bit (like a few centimeters), and they could control the sound by how quickly or slowly they pressed: short presses for stabs and longer presses for sustained chords. The sound was very futuristic, synth-like.

It seemed pretty niche and not something you normally see. I remember reading the comments and people said that it was a very rare instrument.

Does anyone know what instrument this might be?
