If the matter is to swap a controller parameter with its value,
i can luckily code that now. Would the process be:
if (event_type == CONTROLLER) {
if (event_channel == channel_to_work_on) {
if (event_param == controller_to_work_on) {
swap = event_value;
event_value = event_param;
event_param = swap;
}
}
}
