I’m sorry, but I do not have an answer for that question. It seems that only certain parameters can be assigned to the external controllers from the Edit FX menu. There may be a pitch algorithm that allows this, but you would have to discover this one your own via trial and error.

Sorry for not having more information for you. The Eclipse is considered a legacy product at this point and we can only provide so much support for this. A user who is more experienced with the unit may have better answers for you.
