Friday Tip: Using DX and DXi Plug-Ins with Studio One

Using DX and DXi Plug-Ins with Studio One

The DX and DXi (instrument) plug-in formats for Windows were developed in the late 18th century, shortly after the invention of the steam-powered computer. Okay, okay…they’re not really that old, but development of new DX plug-ins ceased years ago when VST became the dominant plug-in lifeform for Windows. Regardless, you may still have some DX plug-ins installed on your computer from other programs, and want to use them.

Like many other programs, in theory Studio One doesn’t support DX/DXi plug-ins. However, it does support shell plug-ins (e.g., like Waves uses). This means you can use a wrapper that makes DX plug-ins look like they’re VST types. With this workaround, Studio One can “see” and load DX and DXi plug-ins because it thinks they’re VSTs.

I’ve tested the following with many DX and DXi plug-ins, from several manufacturers, in 64-bit Studio One. They can’t do sidechaining, and 32-bit plug-ins that were never updated to 64 bits aren’t compatible with 64-bit Windows, but otherwise they work as expected. Here’s how to make your DX and DXi plug-ins productive members of Studio One society.

  1. Go to
  2. Download the zip file
  3. Extract it.
  4. Copy the files dxshell.x64.dll and dxishell.64x.dll to the folder where Studio One looks for VST plug-ins.

That’s pretty much all there is to it. Open Studio One, and you’ll see all the DX and DXi plug-ins—the screenshot shows plug-ins from Cakewalk, rgc:audio, and Sony. The Instruments tabs will show any available DXi plug-ins.

I don’t have a 32-bit system so I didn’t test this with 32-bit DX shells. But if it works like the 64-bit one, you should be covered there as well.

Granted, this is a bit of a hollow victory because if a DX plug-in’s functionality is available with Studio One’s VST plug-ins, you’re better off using the VST versions. But there are still some DX effects that have no real equivalents in the modern world—and now you can use them.

    That’s great…. I have had great success side chaining bass gtr with that compressor. It’s fast and easy to get a good setting. I know people knock the older look of the interface on these but I can dial in exactly what I’m looking for very quickly. The delay is also excellent.

    The Compressor in Studio One can sidechain, so I can cope 🙂 What I’m really happy about is being able to use the Sonitus wah wah and modulation DX effects, which are quite different from the norm.

    Thanks Craig….. I used the sonitus delay and compressor in Sonar quite a bit….. it’s too bad they won’t side chain in this configuration.
