In answer to your original post-
Look at some things like basic mastering, to understand why the exported file is a different level. On your main channel there's lots of options to enable you to get a bit further on. You could look at normalisation of the file, if you're not wanting to get more than some volume raising. You can always raise the level in your daw, of you're in a rush to get something a bit louder. There's a master template that a forum member has designed, so why not try that and reverse engineer it to understand things a bit better. Or maybe it's the way you have your own settings too low and you need to take a look at that. There's a plethora of reasons, and there's a plethora of answers
To your more recent post - every post you've made, has offered you advice and guidance from members on the forum. Most of which could have been discovered by either rtm, watching YouTube vids, or searching here.
To suggest it's the most unhelpful forum is a fallacy.
If you've not had an answer straight away, it doesn't mean people aren't being helpful. It may be that the person to give you the answer just hasn't logged in today, or it may be that the questions are either already answered elsewhere or don't have an answer. To repeatedly bump your thread all day, and complain that you're not getting any answers, isnt great forum etiquette and likely to wind people up. Its also worth remembering that a forum is a communal place, and not a place just for answers to your questions alone.
There's a lot of helpful folks here, who have been around a long time who know the mpc line from the very beginning.
Just be patient and whilst waiting, try to work it out for yourself.
