need a little help w/ older model motif-rack tone generator.  have made performance patches in multi, i.e., splits, layers, etc.  i want my keyboard controller to control the overall volume of the unit, but NOT the individual parts within the multi.  when i move the volume fader on controller, it changes all volumes i have programmed for all of the parts in multi, thus making them all the same volumes.  i have the individual parts volume set to “on”.  i tried setting to “off”, but then i lose volume control from controller.  i would like to have control of the overall volume of the synth, without it affecting the volume of individual parts within the multi.  i don’t want all the parts to be at the same levels when i move my controller fader.  any ideas?
