Looking for a 3+ parallel blender with specific requirements

I'm currently using a Saturnworks 4 Loop Parallel Blender, but I have noticed there are significant volume changes depending on how many loops I have selected. I.E. if I have all knobs set at noon, only having one loop selected will drop the volume to 1/4 of its original signal, but will be at unity volume if I have all four selected. If I have them all dialed to max, then each individually isolated loop will be at unity, but if I turn any of the others on it will increase by x2/3/4 depending on how many I have selected. What I am wanting is something that gives me unity volume when only one loop is selected and then can stay at unity volume when two or three loops are also selected without having to constantly adjust knobs each time I turn a loop on or off. Does anyone know if such a thing exists?

I am only using three of the loops for effects and one for the dry signal, so I don't need something with more than three if it has a dry blend included. The only blender pedals I am aware of that have more than two loops other than Saturnworks are from EHX and Wounded Paw and I am not certain if either will do what I am looking for.
