I might be missing something here, but I can seem to find the use of the Macros being on the Plugin tab. No matter what I do I cannot get the Macros to link to anything in any plugin instrument I load. Am I confusing the role of the Macros here? Are there just for reference incase you’re blending a plugin instrument with a sampled one and you want to have a handy knob to alter stuff in the Sampler while you’re you’re looking at the Plugin tab. 
Perhaps if I haven’t confused myself here, then may I suggest that the Macros operate the raw parameters on Plugin instruments, much like the Doofer does?
