weak signal..please share your ideas if possible

[tritonkorg]

In the project that i'm working on,i use mainly midi and i have some audio loops that are pre recorded with the right levels already...later on i'll have only one vocal track...for my drum track, i'm trying to use BFD and Latin world(from east west) to get a more realistic drum/percussion sound..i start a whole new session for my drum...have tracks for snare..kick...agogo..cymbals...etc...but when i bounce them back to an audio track..in order to import it to my original session where my arrangement is that audio track is very weak and low in quality....i did lots of reading on this, but don't have any idea to how get a strong signal into protools with this midi converting to audio stuff...and volumes are way up there when i'm bouncing the tracks..they sound very weak and hollow...please advise

turn up the keyboard's outputs when you are recording the audio

oh actually if they are sounding hollow try reversing the phase oin some of the tracks.
