Dp4 And Recording Audio Via Usb Interface, i cant get a signal,help!!!!! Options

[dtl1232]

heres my setup: i book g3/500mghtz
m-audio mobile pre usb interface
audio technica mic

heres my problem: i am new to dp4 and i cant get a signal when i am trying to record a vocal track.i know the interfaces of pro tools cubase and deck but this is alot more intense like logic im sure.i have my hardware configured correctly so the input and output are showing mobile pre as selected then i hit the record arrow but no VU meter light or anything.also if i import audio, how do i get it to be on an audio track? in pro tools for example you have the tracks under each other with the waveforms showing as you record and edit,how do i get dp4 to do this? i opened up soundbites and saw the waveforms of the audio i imported, but in order to playback any of it i have to highlight it then it plays but i want to put it on a track and put vocals with it,help!!! i dont mean to sound like a complete retard,i just dont know this interface.thanks in advance for replying and explaining like i'm 5 years old

ok, as for the metering i'm assuming you can hear the audio, but you just want to see a meter to get the proper volume. well, with the track enabled press shift-a and that will bring up the audio monitor. scroll throught the list of inputs until you see your record-enabled tracks(usually they show up with a light red hi-lite).

to export a soundbite you just open up the soundbites window(shift-b) and select the correct soundbite then in the soundbite menu go to "export selected soundbites". here you'll be able to choose what format you want...aif to take into itunes or toast or peak(actualy peak or jam will accept sdII slpit stereo files).
