VerifiedWe verified that this script works as described and does not contain malicious code.
Allows you to control the volume of your system directly from a MIDI control. On Windows, you can also target a specific process or the foreground process instead.

It adds the following parameters to a translation:

Target (Windows): The process name to change the volume of, or “*” for the system volume, and “foreground” for the current foreground application.

Foreground Key (Windows): The key to hold down to override the target with the current foreground application.

Ignore Key: The key to hold down for this script to do nothing while the input MIDI is triggered. 
				
					// if the configured hotkey for ignoring the input trigger is pressed
if ($parameters IgnoreKey) && (keystate ($parameters IgnoreKey))
    return

// Figure out if the max MIDI value for this event is 127 or 16383 (pitchbend)
$max = 127
if ($trigger midievent) == pitchbend
    $max = 16383
// convert the 0-127 or 0-16383 scale from the MIDI event to a 0-100 scale for setvolume
$volume = (round ($trigger rawvalue) / $max * 100)

// if 'foreground' is specified as target, or the configured hotkey for the foreground is pressed
if ($parameters Target) == foreground || (($parameters ForegroundKey) && (keystate ($parameters ForegroundKey)))
    $target = (getfocusedprocess)
// if the translation parameters specify a target, use that instead
else if ($parameters Target) && ($parameters Target) != "*"
    $target = ($parameters Target)

// change the volume of the target
setvolume $volume $target

// on Windows, update the mute state of the target, if necessary
// (on MacOS, polling the mute state this frequently is currently too CPU intense to be worth it)
if (platform) == Windows
    if $volume < 3 && !(getmute $target)
        setmute true $target
    if $volume >= 3 && (getmute $target)
