I just had this same issue while trying to get the knob on the Minibrute to set the tempo parameter on my Studiologic Sledge. It doesn't work at all. Reading these forums shows that the Minibrute doesn't send any of its internal clock data via its midi output. For whatever reason....
Huge bummer, makes me wish I didn't spend this money. My music "career" (i.e., the progression of recordings I've made for myself over the years) stumbled a huge amount when I invested in this synth and got absolutely nothing in return.
