I am running pro tools 10.3.10 on a macbook pro retina with 10.9.5 system.
I had a lot of problems until i figured that this pro tools version can only work with AAX 32bits plugins, 64bits instances are leading to terrible issues with unusable pro tools and unopenable sessions…
I reverted to 32bits version on all my toher than eventide plugins (soundtoys, Slate digital etc ..) and everything is ok.
But i cannot find anywhere weather H910 has a 32bits version or if there is only a 64bits version ?
Yes, you can use the H910 plug-in in any version of Pro Tools higher than 10.3.6. The H910 .aaxplugin file that is installed is a universal binary, containing both the 32-bit and 64-bit versions of the plug-in.
