A free program for Android, by Vincent Burel VB-Audio.
The VBAN Buttons app is a tool that allows you to create a set of up to 24 push/release buttons, that will be used to send audio and MIDI messages to a remote Voicemeeter or other VB-Audio solution, over your local network.
With this tool, you can send a message to start a sound on your device, or to stop it. It will also allow you to send a message to play a specific sound on a particular button, or to stop it.
When you push the button, a request will be sent to your Voicemeeter solution, and when the solution responds, a specific command will be sent to your device.
The app will allow you to set a specific color, title, subtitle, and script for each button, so you can distinguish them easily.
