I really appreciate the replies! I've kinda decided that, probably the smartest (not the cheapest) move in the longer run is to get an Intellijel 7U (104 HP) and get at least 2 quadratts and then some. If anybody is selling theirs and is willing to ship to Finland hit me up :)
Good one on the matrix mixer but the only one I've ever considered was the doepfer one, which is unfortunately huge. I've seen some smaller ones, but they usually lack the possibility for cv control, oh well, maybe one day!
