BTW, does some know if the sounds of the brass pads in "Jump" (Van Halen) 
supposedly made with an OB8/X/Xa, take their flavor from the VCO or from the 
VCF ? I remember i was not very successfull to make such brass on my (now 
sold) JP6. I would be happy to know more about it, since i am in the process 
of building more VCO and VCF.
