Thanks for the suggestion Wavescape!
I also thought about that, but actually I'm having a lot of fun while exploring harmonics and I just love letting my sequencers play some melodies while turning some knobs here and there.
But I get your point, its just two different things I guess. And as far I can see the Sinfonion really gets me in the direction I want to go, even though I'm still open for alternative ideas/modules :-)
