there's nothing wrong at all with the system as the mother 32 is pretty much a complete voice, clouds is probably "the most ambient" sounding module and you don't have much rack space to work with. if you had a larger rack, i'd say you might like rings too for "new age" pad textures but there's no room for it. huh... bummer, taking a closer look at the 32, it looks like it wasn't built for hosting outside modules as i didn't see a mixer.
now, you have a more flexible moog. besides, it's noth the tools you hav, but what you do with them. tracks have been made with less.
