How to link/assign MIDI CC recorded events to a VST/plugin parameter?

Cubase
2

My workaround so far has been using a third party plugin, this of course involves much more steps in the workflow so I would really love to see a way of doing it inside Cubase without using 3rd party plugins:
Here I am using an extra MIDI track, in this track I am sending the MIDI data to

  1. The Sampler Track (to play the samples in function of the MIDI Notes)
  2. The 3rd party Plugin (to receive the E.W. modulation and control the Volume with it)

This Reason Rack Plugin only receives a small amount of MIDI CCs, so if I want to modulate with more different MIDI CC’s then this plugin won’t work anymore.

PD: I was thinking that maybe I could use ModScript for this, but not sure if it really works, I tried making a script using ChatGPT because I have 0 programming knowledge but I couldn’t make it to work:

// Script by ChatGPT to modify a parameter based on MIDI CC input

getDescription = function () {
    return "MIDI CC to Parameter Modulation";
}

// Declarar el número de CC a escuchar (ej. CC 7 es volumen)
CCNumber = 11;  // Número de CC MIDI
paramIndex = 1; // Índice del parámetro (1-8)

currentCCValue = 0;

//-----------------------------------------------------------
processModulation = function (inputValue, numSamples) {
    return currentCCValue;
}

//-----------------------------------------------------------
onCCEvent = function (channel, ccNumber, ccValue) {
    // Si el número de CC coincide con el que estamos escuchando
    if (ccNumber === CCNumber) {
        // Normalizar el valor de CC entre 0 y 1 (Cubase espera valores entre 0 y 1)
        currentCCValue = ccValue / 127;  // Los valores de CC MIDI van de 0 a 127
        // Llamar a onParamChange para modificar el parámetro en Cubase
        onParamChange(paramIndex, currentCCValue);
    }
}

// Función para manejar los cambios de parámetro
onParamChange = function (paramIndex, newValue) {
    // Aquí puedes añadir más lógica si es necesario, como limitar el valor o aplicar efectos
    // Por ahora, se establece directamente el valor del parámetro
    // Cubase automáticamente tomará el valor y lo aplicará al parámetro correspondiente
}
