Happy Thanksgiving everyone.

Please redirect me if this has already been discussed - I couldn't find the specifics I was looking for.

Has anyone created (convolution?) settings - or - does anyone have suggestions/tips for blending instruments from different programs?

Getting a piece from one world collection to work in the same space as an orchestra from another - or getting Ivory to sound as if it's in the same room with that orchestra - is something I'm constantly fiddling with. I realize this is a subjective thing, and particularly problematic where an instrument has already been sampled with sonic properties from a particular space.

Where I have "flat" options with some instruments seems to be key - if I could apply a similar convolution to match the bigger orchestra, for example. Is there anyway to sample or emulate these settings other than by ear?

Thanks for any ideas you have.
