Large Project file size in reaper when saving a patch of vital

So, creating a complex patch in of vital in a reaper project always returns in big .rpp file sizes when saving project. using multiple instances of vital results in 30mb + project file size which definitely could be improved

I wonder if this is an issue for Reaper or Vital?

Can you clarify if you saved the Vital patch before saving the project? If so how big is the patch file?

The biggest culprit for large patch size usage is the sample and wavetables, it’s really nothing to do with patch complexity. Consider clearing the data for oscillators or samples your not using, clean up unused wave source keyframes, try minimizing your samples before you import them into Vital. In short, only put in what your going to use and remove what you don’t end up using.
