Hi list. i would add to it a sync to each vco so the drum would sound constant,but i would use a triger to do this sync job as you dont want to hear the sync pulse. Dave would you considere any efect on the out put ,reverb,delay,or may be a compresor ? thanx Gur Milstein At 02:42 PM 5/27/99 -0500, you wrote: >From: "Dave Bradley" <daveb@...> >A tom or kick has 2 elements - crack and body.
