not sure if this helps and not sure what you guys are talking about but once I figured out how to use the same control for different objects I found that that did not work, the switching of the control to update a different object works great but since my synth used the controls as a storage object for the actual initialization as in a model view controller type thing, i found that when a control was switched to say point to envelope2 that envelope2 was not initialized so I have been back at the drawing board.
