perhaps someone could get cremacaffe to make some ‘skins’ for the pyramid, like they have for the octatrack (the do a few different devices)

I guess they’d need exact dimensions of the faceplate… perhaps @Thibault_Squarp might be able to provide a ‘cad’ drawing they could work off of 
I can imagine quite liking custom designs for the Pyramid.
(Ive been very tempted to get one for my Octatrack… they do look really good)
edit: I’ve shot a message over to Squarp to see if they might be able to help with dimensions - this could be a fun thing.
back on topic:
others have replaced the knobs on the pyramid… they are pretty standard size,
