The Algorythm defines the model of the patch, but the ratios can vary from preset to preset with the same algorythm, just like Envelope- and FM-Amount Settings. I would suggest downloading dexed and look for a patch with the algorythm you want to try out in VCV and then transfer those ratios, envelope-setting, etc. over to VCV.
I always liked Stoermelder Intermix for mapping algorythms. I hope they return to the library soon…
