im new to M.E. and im not sure why. but, im not getting any audio or video signal to record a demo or set. i have cdj2000, djm800, serato and a mac. when i start the record option, it prompts me to the audio box where theres a device box with .. none and an input i can pick from. when i put it on the other input the level reads all sounds around me using the mic on my laptop im not sure if i need something else to record or just dont have the setting right. if theres anyone that can answer this or help out id appreciate it..
