How to use this surface to audio volume fader?

Hello.

I can use this package for midi control.
However, I can't figure out how to use this as an audio volume fader.

I can use the faders on the original surface in combination with a script like this......

///touch
sf.midi.huiFaderTouch({
    faderNum: 1,
    value: true,
});

var value = Math.floor(event.arguments.value * 127);

sf.midi.huiFader({
    faderNum: 1,
    value: value,
});

sf.midi.huiFaderTouch({
    faderNum: 1,
    value: false,
});

Do you mean to apply these things to this Fader Bank? I don't know how to do that.

Please Help me
