Wow ! Thank you very much for the compliment about the mix. I have no idea what is a convolution reverb. So if I used it, it’s a happy coincidence.
I tested a few reverb presets and chose the one that sounded best to me.
Ah I see. You selected a really appropriate one. I'm not super familiar with Reason but I think the RV7000 MkII has a convolution mode. It captures the characteristics of a real life space (like a concert hall) and then applies it to the dry sound. The one I use in Logic called Space Designer is handy for orchestral stuff.
