Hey amop!
Good question! Not sure why i got stuck with only MI products. It started with me buying Warps, found out that it was a cross-modulator, a VCA, and a vocoder. So most of the modules are multifunctional, which i feelt was something for me.
Yes its true, i bought shelves on accident haha! Right now i am using it more as a "EQ" , so i patch the full mix from the Frames to shelves and then to the intellijel Out module, but you are right on that point that its just a space Waste right now. I will look in to that.

I was thinking the same! But the Yarns module can send up to 2 diffrent sequences and also a clock signal (in this case im sending the clock signal to the Grids so i can build drum patterns. Its a littlebit of menu diving, but it gets the jobb done haha!
