Hello,
Prophet V3 was a hybrid of Prophet 5 and Prophet VS.
Now Prophet 5 V and Prophet VS V are seperate instruments. I think that's very good.
The new applications are also rebuilds. Many things has changed.
So the new applications can't use the old Prophet V presets.
You can still use the old Prophet V alongside the new applications for as long as it's possible as it's no longer maintained by Arturia. It's a legacy product.
The old presets can also be used in Analog Lab, when it's set to include Legacy sounds.
