I can still record with the mic into the digi001 and you can hear the music through the headphones in the booth but i can't get it to where you can hear actually hear yourself in real time. I am still working on that. If any has any configurations they have already tried with this, let me know..
There are two ways I see of doing this -
The first (easiest) way is go into your soundcard's mixer software to enable direct monitoring of your microphone input to your Digi's output that the headphones are plugged into (if that is not specific enough, im sure others can chime in who have used that piece of hardware). This will be "realtime", and should have no latency or delay.
The second way is to have Audition monitor the input. To do this, you select the input to record and output to monitor to, then arm the track to record. Make sure Audition's monitoring is internal, it is in the box at the lower right part of the screen (im at work atm, so I can't be more specific). The advantage to this type of monitoring is that you can feed realtime effects, for example, studio reverb, straight into your headphones from the input. You will need to have low enough ASIO latency to monitor real-time in audition, which you should be able to change in your cards ASIO settings.
If you are just looking to simply monitor your vocals while recording, the first option is probably your best bet.
