How to use itIt's a command line tool, run it from anything you can call a command from. You could run it to Play, Pause, Play a source, turn the volume up or down. Theater or Music applications that enable you to run external commands for example. Home automation? "HALRAD play me a tune"...
Known working / tested scenarios:
Create desktop shortcut or pin shortcuts to the start menu for Play, Pause, Vol Up , Vol Down, or play your favorite sources.
To simply start the current source playing the short cut target might look something like this: c:\tools\slacmdr_win-x86_r2.exe 192.168.0.15 groups -Play you could assign a hotkey to the shortcut to execute the command to run the shortcut via a hot-key combination.This is handy on a small screen or touch screen enabled device as an alternative to slPhantomTray. 
Assign commands to Buttons on your elgato Stream Deck.
You can use the 'BarRaider advanced launcher' to run a command when a button is pressed. That command in this scenario is to slaCmdr.TODO: investigate a Stream Deck plug-in, but for now opted for a command line approach first for its simplicity and re-usability. The slaCmdr command line is already working. But could be better.... by displaying status (Volume, Play State) via the buttons. The Phillips HUE plugin looks nice but the C++ CPU plug in might be a better starting point. slaCmdr.exe contains an icon resource library
use these to customize your shortcuts icons.

(New) for R20 slaCmdr supports mapping device IDs to user-friendly names using a JSON file named device_names.json.
This file is created in the same folder the program exe is located the first time it is run. You can delete the file and it will be re-created.
This allows you to see meaningful names for your Devialet Phantom devices instead of raw device IDs in the CLI output.
Place device_names.json in the same directory as slaCmdr.exe.
{
"DeviceIds": {
"9127538b-79cc-56db-84f1-09807255eaa7": "arch",
"e6e97c6f-0ac8-5a35-b68d-52f70ce7d7af": "left",
"c8a05c46-3fc0-5111-aa47-56126ffd2d3c": "dialog",
"a7e4a870-a141-529b-b564-13d71d18fc7e": "right"
}
}
When listing sources or devices, slaCmdr will look up each device ID in device_names.json and display the friendly name if available. If a device ID is not found in the mapping, the raw device ID will be shown.
device_names.json with any text editor or use 'de' device edit comand from the CLI.API rubricReference to the related Devialet APIs for the scenarios:
