I was surprised to find out just how many years ago it was that I first checked out DDMF's Metaplugin — my review appeared way back in SOS May 2011. Since then, this most handy of problem-solving plug-ins has matured considerably. Not only is the interface more user-friendly, but this VST/AU/AAX/RTAS plug-in (for Mac/Windows) is now capable of hosting VST2, VST3 and AU plug-ins, bit-bridging, and up to 4x oversampling for the whole plug-in chain being hosted. It can also deliver DAW automation data to any parameter of any of the hosted plug-ins, and supports DAW plug-in delay compensation. And what's more, Metaplugin itself isn't all you get, because bundled with it are three other utility plug-ins that can be used either in your DAW's insert slots or within Metaplugin: the M-S encoder/decoder and multiband splitter came with the original version, but there's also now an audio routing plug-in called SendIt — and for users of some DAWs that last plug-in alone could prove worth the price of admission.

Metaplugin itself is essentially a plug-in wrapper that provides a blank canvas in which you can organise and route your own third-party plug-ins freely. By default, the GUI displays the audio and MIDI inputs to Metaplugin and outputs from it. It's your job to add plug-ins and link them together. You can load plug-ins directly, drag them from Finder (and presumably likewise from Explorer on Windows... I tested Metaplugin on a 2018 MacBook Pro running Mojave), or automatically scan chosen folders to populate a plug-in browser in Metaplugin itself. You can also right-click to insert a plug-in, duplicate plug-ins, and so forth. Plug-ins can be placed anywhere on the main section of the Metaplugin GUI, and the hosted plug-in's inputs and outputs are made visible graphically. Creating a signal chain is a simple matter of dragging and dropping from the Metaplugin inputs to the inputs of your plug-ins, dragging from one plug-in's outputs to the inputs of the next plug-in in your chain, and from the last plug-in to Metaplugin's outputs. The links between plug-ins are indicated by graceful, curved lines — and when you hover over one of those lines, you'll find a control to boost or attenuate the signal level.

It's all very intuitive, and creating complex effects chains (eg. with feedback loops, parallel processing and more besides) is a doddle, and you can save these as patches in your DAW. Cubase/Nuendo users in particular might be interested to note that Metaplugin will reveal the external side-chain inputs of any VST2.4 plug-ins that have them. And coupled with SendIt (of which more below) that can grant you access to side-chaining with VST2.4 compressors and gates — Cubase normally requires VST3 plug-ins for side-chaining.

Slightly more complex is the parameter automation, and that's because the host DAW obviously can't directly 'see' the plug-ins hosted in Metaplugin. DDMF get around this by providing an assignable list of parameters — you map whichever ones you want to whichever parameter you wish to automate. This is obviously slightly more fiddly than accessing parameters directly in the DAW, but it's a sensible approach, and if you only want to automate, say, three parameters in a chain you won't have to wade through them all in your host DAW.

So what of SendIt? Well, this is reminiscent of the old freeware 32-bit Senderella plug-in that I used to use as a problem solver. You require two instances, one to act as a sender and one as a receiver. The sender instance can be placed anywhere where there's an insert slot — within Metaplugin, directly in your DAW, or even in another piece of software entirely. To return to that Cubase example, you could place the sender in your kick track's post-fader insert slot, and have the receiver feed the external side-chain input of a VST2.4 compressor inside Metaplugin to duck your bass part. When you stop to think about it, it could be useful in any DAW, though, as I can't think of a DAW that allows you to send from any point in the signal chain (such as from between two insert processors). You could, for example, use a send instance as a meter tap, moving the sender instance to get a reading on your meter from any point in your DAW.

I did make one suggestion to the developer that was warmly received, so I have high hopes that it will be implemented in the not-too-distant future: SendIt currently features a Thru tickbox that allows audio to pass through the plug-in as well as being sent elsewhere. My idea was to add a blend control, to balance the thru and sent signals — it would make it possible to create a 'BBC echo mixture'–style send (see here for details: http://sosm.ag/send-and-blend) very easily in any DAW.

Some of the other uses of Metaplugin are obvious. You can use it as a wrapper, for example to host VST plug-ins in Logic, or VST/AU in Pro Tools. It can also act as a bit-bridger, breathing life into 32-bit plug-ins (if your OS allows them). But really, the most fun is to be had when you start exploring what can be done with the ridiculously flexible routing inside Metaplugin; your imagination really is the only limit.
