Newbie alert - have a new MBox with ProTools/LE 6.7, in a Windows XP PC with a SoundBlaster card. I can hear guitar out of MBox but cannot hear any metronome/click from ProTools (I can see no "MBox" option for routing the metronome). I can hear the metronome out of the SoundBlaster, but no guitar. I created a click track in Finale, Saved As a MIDI file, imported that into ProTools. It created 16 MIDI tracks (I'm not sure why...); track 10 was the only one that showed any data (a solid black line). I deleted tracks 1-9 and 11-16, but could not hear anything from track 10 from either the MBox or the sound card. We cannot get the most fundamental scratch track recorded (which is very frustrating...) because I cannot find how to get the metronome sent to the MBox. I will be happy to be humbled if this is painfully easy, but we're just not getting off the ground here. I look forward to your suggestions.
