Whew I'm confused. LOL! I use Sonitus in Sonar 64 all the time. I had figured they have their own thing going on as a 64 bit plug in Sonar, no? Them and some "Cakewalk" plugs are actually the only DX plugins that show up when I use Sonar 64. All other DX plugs don't even appear. So I assumed they had 64 bit versions.
If these plugs are not officially in a 64 bit format, are we really losing anything by using them? For years we used some plugs that weren't x64 while using x64 and we survived quite well. Is it really that big a deal?
I have a few killer reverb plugs that nothing touches in my VST library. I sometimes use Sonar x86 just because of them. If something works....and my system isn't being bogged down....and I'm not hearing artifacts and my stuff sounds the way I want...isn't that all that matters?
The only benefit I see in x64 is a little less processor activity. With a fast enough system, it's not even super beneficial to me unless you're using loads of sampling libraries. But that's just me.
