Control groups in control declarations

[notator]

Should controls be grouped in control declarations? for example:

controls =
[
    ...
    {
        { name: "filterEnvelope attack", index: 28, defaultValue: 6 },
        { name: "filterEnvelope decay", index: 29, defaultValue: 8 },
        { name: "filterEnvelope sustain", index: 30, defaultValue: 6 },
        { name: "filterEnvelope release", index: 31, defaultValue: 9 },
    },
    {
        { name: "volumeEnvelope attack", index: 46, defaultValue: 3 },
        { name: "volumeEnvelope decay", index: 47, defaultValue: 19 },
        { name: "volumeEnvelope sustain", index: 48, defaultValue: 86 },
        { name: "volumeEnvelope release", index: 49, defaultValue: 6 },
    },
    ...
]
