I too am unable to use Liquid Mix in Cubase 64 bit, both C6 64 & C764. In C6 I get the delay. In C7 I got a bunch of pops and crackles. I contacted João from jBridge and he sent me a little utility program that confirmed there was nothing wrong with the LM dll.
Long story short, I gave up on trying to render LM in Cubase 64 bit. LM seems to open & run properly but won’t export without serious issues. João suggested I jBridge my larger sample VSTs to address the ram separately allowing more use of my ram that doesn’t conflict with Cubase 32 bit.
So I jBridged my 32 bit versions of Addictive Drums, Steven Slate Drums & Groove Agent 3 to jBridge 32 versions. I don’t really understand the advantage or disadvantage of jBridging 64 to 32 rather than 32 to 32.
Maybe someone could explain that?
