VB-Audio Matrix Coconut - audio interface aggregation on Windows that actually works

VB-Audio Matrix Coconut allows you to use multiple audio interfaces that are connected to the same computer at the same time by aggregating all their inputs and outputs into a single virtual ASIO audio device that can then be selected in your DAW as its main audio device. You'll have all the different inputs and outputs available simultaneously.
This Matrix app can even sample rate convert non-word-clocked devices on the fly, for instance, a USB keayboard's audio so that its audio can be aggregated, too.
First, you put all your physical audio devices into pre-defined device slots in order to let the Matrix app take control over them. Then, you activate one of the selectable virtual ASIO devices it provides that disposes of enough channels and route all your physical audio channels coming from different hardware interfaces to it. Finally, you select the virtual Matrix ASIO device as your DAW's audio device and you will be able to use all of your hardware interfaces' inputs and outputs combined - all interfaces will behave like a single large one.
The total number of aggregated audio inputs and outputs is a whopping 3016 x 3016! Until recently, asio4all was one of the few apps for Windows users that somewhat tried to accomplish this task in a very modest and rather unreliable manner. The Matrix app has been working for me without any audio glitches for several weeks now, aggregating appr. 100 audio channels originating from different USB keyboards, Windows apps and audio interfaces at a buffer size of 128 samples! The Matrix also offers VBAN, an audio-over-LAN protocol that allows you to send and receive high channel counts of uncompressed audio via the LAN and also aggregate and route those just like all the aforementioned ASIO, WDM and MME audio channels.
VB-Audio Matrix Coconut is available as donationware (30-days trial period from here: https://vb-audio.com/Matrix/coconut.htm
The license is tied to one computer and may require re-activation if important pc hardware changes or a new operating system is installed. One re-activation is included.
Even though my dante audio network gave me limitless routing possibilities among Dante audio devices, adding VB-Audio Matrix Coconut has expanded routing options considerably.
