Spotted over @ Matrixsynth, is this unusually fleshy-looking fingerboard synth known as the Imesco polifónico. Not much info aside from what the demo vids show us and some incidental descrips translated from YouTube-

this is the same instrument that was introduced some time ago, now a little over, also lack enough practice since the video was done in haste,

[…]
with a little practice you can play continuously, alternating between the surface and color sector

Fairly certain I saw one of these used by a lounge act in Existenz. More interesting instrumental creations can be seen on imesco’s channel.
