HYBRID support is coming this month to the DN-S3700. Watch the video.

However, Serato and Denon have come to an agreement to NEVER create NATIVE SUPPORT for the DN-S3700. So the platter will work in HYBRID mode, but the LED backlit buttons and display will never work.
I don't know the reason behind this. Maybe Serato doesn't have a few days to spend on Native Support in HYBRID. For MIDI, the 3700 is almost identical to Denon's 19" Rack Mount DN-HC4500 which has Native Support. I don't see what the big problem is?
