Hi to everyone,
I’d like to briefly comment on this and hope I can help to shed some light on this topic.
During the integration of elastique Pro into Cubase 6, we have also tested using it for VariAudio.
One result of these tests was that elastique Pro had troubles dealing with the rapid pitch changes (pitch curves) that appear in the context of VariAudio. This would lead to nasty artifacts or unexpected pitch fluctuations.
Another result was that for monophonic audio material, the quality of elastique Pro was not superior to the quality of the Standard - Solo algorithm preset. This is something you can verify for yourself by comparing the elastique Pro presets and the Standard - Solo presets applied on monophonic material (outside the context of VariAudio). Please let me know if you agree or disagree.
I understand that one might be led to believe that elastique Pro sounds superior to any of the Standard algorithms in general. However, this is not always the case. For monophonic material, the Standard - Solo presets performs really well. The elastique Pro algorithm has its strongest advantages when it comes to polyphonic material. For monophonic material, I would say, it is about on par with Standard - Solo.
Based on these results, it is understandable that elastique Pro has not been added as an option for VariAudio yet.
If this changes in the future will probably depend on where we want to go with VariAudio.
