no problem mate its hard to compare really, you see you can compare CD and Vinyl Turntables with each other because they have many similarities and well the CD turntable derived from the Vinyl Table really but as for comparing Midi controllers and CD/Vinyl its hard it also depends on what software your using and how your using it, most midi's and software have a feature called "Auto Sync" which basically Does all the work of a DJ for you, all you need to do it press play and stop....we do not like this feature Without personally using Vinyil tables before i would say they are definitely the hardest of the 3, but both CD and Vinyl you have to Cue your tacks up and beatmatch etc where as Midi's you can do both but its not so much needed/necessary because you can just click the waveforms and see the BPM and Beats as they come.... dont get me wrong there are plenty of Big and highly skilled DJ's that use Midi Controllers and software and are Quite Awsome at it, the 1st name coming to mind is Carl Cox, if you dont know him check him out, he is a Traktor Rep Hopefully a few other members will jump on this thread and help me give you some insight i was once like you, but until you use different types of gear its hard to know the difference really
