im a little confused by what he means….
Are u wanting to use a turntable and use like Timecode with it? The denon Mc6000 does not support timecode signals.
and will have to use another Controller or get a NI Audio 4 or 6 or something.
All of ur other questions are very specific to what software u are running…If it is traktor…any controller will work in addition to what you have as an FX controller as it is all just MIDI.
No Actual Turntable will work with the MC6000 as MC6000 doesnt support timecode as far as i know.
You can however use something like the new Denon SC3900 that is a controller/motorized platter table and use that as a controller, and have the turntable feel to it.
