Denon (supposedly) uses standard MIDI just at high-speed (at USB 2.0 speeds). Serato has a customized high-speed MIDI for their ITCH products (for Numark and Vestax specifically). Native Instruments, Serato, and Denon have each made a custom way of addressing this lag. ALL standard MIDI devices have this lag on jog wheels because the data transfer is too slow AND the resolution of data being transferred is too low. What you're describing isn't latency of digital audio, but rather a (rather large) lag due to MIDI and jog wheels. But finding that the delay with the jog wheels/fader is more than I expected. I recently purchased a Vestax VCI-400SE.
