I've problems with setting var sends for individual parts.
As an example, I took a standard CFX Concert Grand and added a elek guitar part (Breakback mountain).
Now to make that guitar sound better to my liking I changed the common variation effect from the default to chorus - 2 modulator (similar as it is done in the original performance for Breakback mountain)
My goal is that only the guitar part will go through this effect and the piano parts will only go through the reverb.
So in the mixing screen I set all the piano part var sends to 0 and only give some send value to the guitar part.
Also I give the var return a value, say 64. To my ears I seem to hear that not only the guitar part is processed by the variation effect but also all the piano parts, even though the var sends are set to 0. What could I be doing wrong here?
