Hi, I am looking for a good entry level monitoring headphone for recording and mixing. For hardware, I have M-AUDIO FAST TRACK and AT2020. For software, I have GARAGE BAND and PRO TOOLS SE. I always use GARAGE BAND and PRO TOOLS SE is completely new to me. I tried to play music on PRO TOOLS SE but it did not come out any sound at all. I assume it require me to plug a headphone directly to the FAST TRACK instead of my MacBook Pro. Thanks for everyone who is willing to help.
