/**

function HandleMIDI(event) {

    if (event instanceof Note && event.channel === (1 + GetParameter('Channel'))) {
        var config = PluginParameters.find(function(config){
            return config.defaultValue == event.pitch
        })
        if(config){
            var pitch = event.pitch
            event.pitch = GetParameter(config.name)

    }
    event.send();
}

The configuration array at the top will create a set of sliders, one for each specific midi drum pad zone (1-7). Our zone sliders will shift the incoming notes for each zone.

The default value of each zone is the incoming note value we need to look for.
The selected value is the pitch will we map the note to.

The Handle Midi function will test to see if the incoming note matches our selected channel. The array of channels starts with an index of Zero, so we must add one (+ 1) to shift that value to the proper starting index of midi channels (1-16).

Then we can find the setting for the zone, based on the default note value contained in the configuration array.
We then set the incoming note with the target pitch.
