Thank you for the idea! 
still Iām getting this conflictā¦
I suppose the problem is caused by the Index value. Seems to me that Index 1 for Violins is automatically recognized as slot for Violins II (in case the IVP isnāt activated before the loading of Violins II)
P.S: Yep, I was correct for the Indexā¦ If you create Violin I then divisi in 4 and activate IVP, the Port: 1 Ch: 3 will be occupied and after that use then Add Ensemble: vln, vla, vc, cb and turn them into section players. That way Violin II will take itās proper slot in the Endpoint Configuration list.
