The problem with creating a template that already achieves this goal is that you would still have to transpose the MIDI data which isn't really a big deal but it adds a step and becomes time consuming.
What I was thinking was, within VEP, you insert two VIP Pro instances of say solo violins. Both instances would be the solo violin but the second instance would be the transposed instance by whatever the user chooses, ie 1/2 step, whole step, up, down, etc.
With that second instance the transposition occurs internally so the user doesn't have to think about it. In other words, when you play a C6 in the first instance you hear the original C6 recorded sample. When you play a C6 in the second transposed instance you hear the C# 6 sample transposed down to C6 because the software makes the transposition internally. So sonically you wouldn't hear much of a difference between the C6 of the two instances but the second instance is transposed. This method would dummy proof the process and perhaps make things easier for notation software so you don't have to print the score out as originally written then go back to transpose the 2nd violin for playback purposes.
Three things come to mind:
1. The second instance would be off kilter by a 1/2 step down in the example above, meaning you would loose the very top note but gain a 1/2 step on the bottom.
2. Since the Special Editions are sampled at whole tone I don't know what the implications of this transpose trick button would be.
3. The VSL software engineers have been able to work some wondrous magic over the years and I would imagine that this wouldn't be too challenging but I guess that's why I'm not a software engineer😃
In the end, all this is is an anti phasing issue which I know has been achieved in other music software applications.
