Question

Because Studio One 4 is only compatible for 64 bit.

Please tell me someone who bought it and tried to it?  

Answer 1

Studio One 4 is 64-bit only, so 32-bit plug-ins will not work with Studio One 4. 

Studio One 3 was the last version that supported 32-bit plug-ins.

Answer 2

You can use Jbridge.  It works perfectly :

Answer 3

Are there any free alternatives to Jbridge? I'd really rather use that. In fact, why does S1 not support 32-bit plugins anyway? I came from FL 11, and there I could use both plugins together, no problems.
