I found out an alternative way to achieve a VI 2 instrument in VEpro 2 retuning the instrument to avoid phasing with the interaction with VI 1.
I am using the Special Edition library for this.
The system works out for me and I am curious to know if Vienna will agree and approve it:
this is how it works:
in VIpro 2 load the SP ED Orchestral Strings/Strings violins matrix.
This is going to be your 2nd Violins after you do the following FOR EVERY SLOT of your matrix violin:
1. in advance view, select the VI-14 staccato slot, select Edit, under Semitone select 2.
2. In Basic view you have to activate if not already visible a Pitch Bend fader.
For that you select an empty channel of the Controller mixer and in the lower square assign "pitch bend" after in the upper square assign "wheel". The fader value must be 0.
remember that this must be done for every single slot in you matrix. Once is done you can save the matrix as your SP ED VI2 personal matrix
Thats it!
Now when you play VI1+VI2 in unison you should not hear any phasing because VI2 has been retuned to play on the next near sample.
PD.:I use this configuration with SIbelius 7 and I don't have to do anything in SIbelius at all to make it work. All The programing is done in VIpro2. Once is done is saved with the VEpro project and you don't have to program it never again.
I hope this was helpful
good luck
