Pro Tools support

OP-X PRO-II offers no AAX or RTAS version (only AU and VST3 in Mac and VST2 and VST3 in Windows) and so can't be used in Protools directly. There however are tools which allow to wrap plugins in other formats for the use in the AAX or old RTAS interface.

AAX - Protools 10 upwards

There are so-called meta plugins which come in AAX format by themselves and can load other formats like AU, VST or VST3 within them, which allows to use an AU or VST plugin within Protools. These are the existing options we know of:

Blue Cat's Patchwork:

DDMF Metaplugin:

Note that we haven't tested any of these by ourselves so we can't give any guarantee that it will work. We however know of some customers who successfully use OP-X PRO-II in Protools AAX Mac with Blue Cat's Patchwork meta plugin. The best check it out by yourself using the free demo versions.

RTAS - Protools 9 or older

Note that the RTAS interface isn't supported anymore by Avid and there also seems to be no support anymore from Fxpansion for their VST-to-RTAS adapter. So what's written below refers to the past.

OP-X PRO-II used to work well in Digidesign / Avid Protools 8 when converted to RTAS with the newest Fxpansion VST to RTAS adapter. Once converted to RTAS the synth used to work like any other RTAS instrument and was available in the instruments list.

Note: Will only work in Protools Windows (not Mac)!

You can/could buy the VST to RTAS adapter here:

Once converted to RTAS the synth used to behave like any other RTAS instrument. It would show up in the instruments list and you also could automate every parameter.

Here's a short video that shows OP-X PRO-II in Protools 8 with some automation applied to the filter cutoff of the synth:

Protools 8 Demo:

Multiple Instances:


Note this old guide only refers to the former Fxpansion VST-to-RTAS-Adapter. RTAS has been discontinued by Avid since Protools version 10 and there seems to be no support anymore for the old Fxpansion adapter. So this guide only is useful if you still use an old Protools 8 (or 9) and this only in Windows. So here's the former guide:

Install OP-X PRO-II to the place you want to pick it up then with the adapter. Don't move the dll after installation! You would lose all banks doing this. If you move then only move the whole "SonicProjects" folder, or at least both the "OP-X PRO-II.dll" and the "OP-X PRO-II" folder together since they build a functional unit and need to be in the same folder.

If you install the VST to RTAS adapter before and you don't use OP-X PRO-II in a VST host too then you could point the installer directly to the Fxpansion VstPlugIns folder which is located in:

C:\Program Files\FXpansion\VST to RTAS adapter\VstPlugIns

Of course you also can install the synth to any place of choice and then browse to this folder in the "search for vst plugins" area in the adapter software. Simply make sure that the plugin with all its components will remain there.


Windows Vista and 7: Launch Protools as administrator to license the synth.

If the synth resides somwhere within the system's program files folder then launch Protools as administrator to license the plugin. Otherwise there could be a "can't create license file" error message. To do this right-click on the Protools application shortcut and choose "Run as administrator" (shield symbol). After lisening the synth you need to unload and reload it once until it will start working.
