Groove Agent 5 and Halion Sonic 3 updates break ability to insert application in both Logic Pro X and Studio 1

As mentioned in header that the most recent updates for those programs break the ability to drag the VST in Studio One 4 .5 to instantiate or also install the audio unit versions from the Logic Pro X drop down header.

Both methods of instantiation results in an error code indicating no valid license detected.

It appears reverting back to elicenser control 6.1 1.6.1 253 does work though.


I would recommend to post this to the VST Instruments, Virtual Effects Plug-ins and Add-ons thread.

Hi Martin,

Any reason why the new eLicencer prohibits the drag capabilities in Studio One 4.5 to insert these two Steinberg VSTis?


I dunt know. Therefore I would recommend to post it to the relevant thread. I believe there are people with experience in this area.

Just make sure you have installed Groove Agent, not SE. Same with HALion Sonic, make sure you have HALion Sonic SE license available, please.

Yes I have purchased and installed the full versions of both GA 5 and Halion Sonic 3.
