Passing arguments with Util.command() not working as expected

[hhartkopf]

Hi, first of all thank you for this nice little tool. I'm currently trying to control the output volume of a Mac by using the switches on my MIDI keyboard. I'm using this command: receivemidi quiet dev "V25 Out" jsf AdjustVolume.js and the AdjustVolume.js script looks like this:

if (MIDI.getControllerNumber() == 49 && MIDI.getControllerValue() == 127)
{
    Util.command('AdjustVolume --increment --device-name "Built-in Line Output"');
}
else if (MIDI.getControllerNumber() == 48 && MIDI.getControllerValue() == 127)
{
    Util.command('AdjustVolume --decrement --device-name "Built-in Line Output"');
}

The AdjustVolume command comes from https://github.com/jonomuller/device-volume-adjuster and is working fine in a regular shell but invoked by the script it throws Device name not found. so i guess the device name argument is not passed correctly. I already tried swapping the single and double quotes and some other things like escaping the quotes but i could not get it to work. I'm not an expert in JavaScript or C++ so am i missing something obvious here or how is Util.command() supposed to be used?
