Set up your drums and microphones to your personal liking. This will most likely be the same set up you would have if drumming in a live show or concert. Connect the female end of each of your XLR cables to the mics and then connect the male end of each cable to its own input on the interface.
Open Pro Tools on your computer and create a new session or open a recent session. Click on the "Tracks" tab located in the menu bar at the top of the screen and click "New..." A small box will appear and will have "audio" as the default type of track, "mono" as the default input signal and "samples" as the default recording method. These should be left alone and the only thing that should be changed is the number of new tracks that will be created. Change that number from one to the same number of microphones you have connected to the interface.
Press and hold "control" and then press the "=" button on your keyboard to switch your view to the mixer, or click on the litte gray box immediately above the highest track to open a menu. Then click on "inputs." The mixer will already show the inputs. Click on the "input" button for the first track and hover the mouse over "interface" to pop open the menu showing the interface's inputs. All active inputs should be yellow instead of gray. Assign the first track to the first active input. The inputs will usually be represented by two numbers. This is normal and is set up this way so there is always space for stereo recordings. Set the rest of the tracks each to a different active input.
Look at the interface and determine which input is connected to the mic for each drum. For the drum attached to the first input, which will most likely be "input 1" or "input 1-2," find the track that has the same input numbers and double-click on the white "name" box in the upper-left corner of the track. If the mic is connected to the snare drum, name the track "snare." Continue doing this with the rest of the tracks, giving names according to the drum that corresponds with each track.
Click the red "record" symbols which are located below the "name" box on each track. The buttons will flash red and the green decibel meters should activate on each track to let you know that they are receiving sound from each microphone. Now click the bigger "record" button, which can be found in the main toolbar in the upper-right portion of your screen.
Press the spacebar or click "play," which is located next to the main "record" button. Pro Tools will record all of the tracks with flashing red "record" buttons at once.
