I did not buy the Cartesian system outright, but built a modified version of it, augmenting it with a Pressure Points, omitting the STO (have enough other VCOs), and omitting the Rosie.
I’ve got a few other MN modules, but they’re not part of that system.
It’s a great system. The Telharmonic is really cool, the LxD modest but beautiful sounding, and the Rene + Wogglebug combination is totally essential in my opinion.
But I split everything up in to two groups: the Wogglebug + PP + Rene + Teleplexer are in a MN control/output skiff, along with a line out/HP module, an Erbe-Verb, and a couple other things. The balance of the Cartesian modules are in another larger case with various other things.
