volume control isn't necessary, the difference in feedback isn't significant with how little objects there are in the intro (the only place that would really warrant any volume control)
This sounds like you just want to avoid getting the map disqualified. The intro is significantly calmer than the rest of the song, it's also mapped with significantly lower volume in the other diffs of the spread, so please make that consistent.
I would recommend raising up the overall volume for the whole spread by like 10-20% though, since 30% and 60% seem a little low for their respective sections.
