o.k. i can see where your at, download this free plug in/
rnd | inspector / install it and run it as an insert on every track you record, then adjust your external source so that the plug in peaks at -18 dbfs and your good to go, then everytime you add some e.q., compression ,ect. check the inspector plug in to see where your at..dont go to close to 0dbfs, leave some headroom for your final mix or mastering... personaly i prefer to record around -12 or 14 depends on the source. note..if your rig only has external monitoring.., you may have to record a short piece and then check the plug in on playback to see where you are,..this will get you recording at proper levels and you can work on understanding why your doing it as you go...hope this helps.. good luck..
