1) Create an audio channel(s). If stereo, make two audio channels and pan each hard (100) left and right. 2) Connect the outputs of your MIDI device (keyboard, drum machine, etc.) into available inputs of the 001. 3) Set the input of the audio channel(s) to the input(s) you have routes into from your MIDI device. 4) If you are not actually recording yet but want to monitor the signal through an audio channel(s), make sure that Pro Tools LE is set to Input Monitor only under the Operations menu. 5) Record enable your audio channel(s) and hit play/record.
