So I just updated to Bias FX Professional which has an IR loader. One thing I don't like is it truncated all the file names so it's hard to tell what I'm looking at and seems really disorganized.
I almost end up avoiding using the IRs I've purchased because I get overwhelmed with all the files. The celestion IRs I have include: Bitrate folders, each containing different sample lengths, different mic selections within those folders. If anyone has a system for organizing some of that stuff so it's actually useable, I'd love to know how you do it!
