I believe if you use 32 bit plug-ins in a 64 bit DAW, then you need a bridge.
I don't believe you can use 64 bit plug-ins in a 32 bit DAW.
However i believe it's best to use DAW and plug-ins in the same bit like 32 or 64 bit on both.
You say you don't have sound in stand alone mode. If you have set up the audio settings correct, then there should be sound.
If you are sure you use the correct plug-ins types and bits, then it should work. And if all other V-collection applications work for you both as stand alones and as plug-ins, then i assume you do, and then this is a mystery to me.
You can check and see if your plug-in is updated. If not, then try to update.
Perhaps there are issues to use some applications with your DAWs/ versions or on certain MAC OS. I suggest you contact Arturia support about this.
I don't use Logic X, Ableton or MAC.
