64 bit version of Soundop is available now, you may choose to run 64 bit version to load 64 bit plug-ins.
I switched to the 64-bit version of Soundop recently, and I’ve definitely felt a boost in performance, especially with some of my heavier plug-ins. The loading times are shorter, and it just feels more stable overall. If you’re using a lot of 64-bit stuff, I’d say go for it!
