Thanks for the feedback already.
I really liked the sound of 'Shelves' as well as its flexibility, but maybe i found another option with the Polaris. I didn't realized that the wavefolder has two inputs, i was more amazed by the sound of it.
I actually chose the Quad VCO because of its LFO features, but it's really taking a lot of space, so I switched it for a simple VCO and a proper double env-generator.
originally I thought of the VC.mixer as my output mixer ,but probably it's better to have a proper one instead.
so here comes the update:
