Hi
If you are talking on using prg. changes in the Vienna Instruments Pro, then yes! Moving a patch in the column to the left will shift down the folloving patches but the numbering of the patches that correspond to the prg changes will remain.
So if you have 2 patches:
1 legato2 staccato
and now drag the legato patch below the staccato patch you will have:
1 staccato
2 legato
