Matrix CLI

[Andew212]

Hello, is there a way to access the Audio Matrix CLI externally?

Eg, does it expose a TCP server on a certain port or anything like that?

I would like to be able to control it from another program.

Thank you!

Thanks Vincent!

However I am still a little confused. So once VBAN is on, it opens a UDP server on port 6980 correct?

And then I should be able to send packets to it using the TEXT type to send CLI commands?

Could you help me with an example packet? Once I get the first one I can go from there.

If I want to send the cli command Point(ASIO64A.IN[6],ASIO64A.OUT[3]).dBGain = 0.0;

Would I send a packet as below:

VBANR\00\00\10Point(ASIO64A.IN[6],ASIO64A.OUT[3]).dBGain = 0.0; //sent as ASCII

to port 6980 as UDP?

I am using packet sender (https://packetsender.com) to test, but if you could suggest something better that would be great!

Basically yes, but if you don't program it, you may use MacroButtons (installed with any Voicemeeter).
and define you request like this for example:

SendText("vban1",Point(ASIO64A.IN[6],ASIO64A.OUT[3]).dBGain = 0.0;);

see user manual page 54: https://vb-audio.com/Voicemeeter/Voicem ... Manual.pdf

Thanks Vincent, I have got this working now.

My problem was I didnt realise that VBAN stream 1-6 were audio, 7 was MIDI, and 8 was ascii.

Used the correct VBAN stream and have control now.

One more question. I can set all the commands I want, but is there a way to query the state of a command without changing it? So like can I read the current state of a point in the matrix?

Thank you!

Here is a CLI program that can be used to send VBAN-TEXT instructions to Matrix. There is an example in the README.

If you're not sure how to build the program I've included executables in the repo's Releases section.

That is extremely helpful, onyx_online!

Can I repeat Andrew's question which was not answered as far as I can see - is this command channel strictly one way, or is it also possible to read parameters from Voicemeeter and Matrix?

The vbantxt-cli can only be used to send requests.

To receive data a client program must subscribe to the VBAN RT Packet service.

Vincent has provided an example of this in the vmr_streamer source code:

As far as I know this is currently only possible for Voicemeeter, but not Matrix.
