I think it was all removed. I can't even open Cakewalk anymore because it's missing the executable in latest branch.

why aren't there any Cakewalk products on Steam anymore?

I don't know - there is no announcement. What make me curious is why there is still a store page for Cakewalk. Normally when games/software get removed from steam, their store pages redirect to the Steam Featured page - except Cakewalk Loop Manager for some reason.

OMG, guys, on Cakewalk site posted THIS:
