Loop Behaviour

Evening all!

Quick question as I’m not sure if I’m going nuts or not…when running a loop during a mix out from a playing track I find that unless I switch the lead deck over to the incoming track the loop will always drift, this has always been the case since I got my 6000s but I don’t ever remember doing it when I used Traktor or Pioneer, is this a Denon thing or a glitch or what is it?

Same thing when preparing tracks in engine.

Any thoughts appreciated.

I don’t use sync so perhaps not best to answer this specific question, I do however use loops all the time and never noticed any kind of drift on them providing my loop is the right length so maybe some part of the sync process?

Yeah guess it must be, seems strange behaviour if it is related to sync.

Are all your tracks gridded correctly? Are they all good quality downloads from download sites? No vinyl rips?

The only thing I can think of is your grid isn’t in exactly the right place, and that’s far more likely to happen later in a track, specifically if that tracks bpm has wandered slightly from start to finish (live drums, vinyl rips, old house tracks poorly mastered etc)

Yeah everything is gridded spot on, I’m very experienced and particular with file formats, all purchased legitimately or promos. I only use engine for initial analysis then into MIK then over to lexicon to tidy up any data, analyse and then back into engine, super clean files.

It’s not a big problem, I’m just curious as to the behaviour compared to other platforms. Also I don’t play vinyl rips, just modern day prog and organic house.

Try it with the software in engine and see if you get the same results.

FWIW I’ve had just as many problems with loops not lining up in Serato and RB as I have Engine… I think it totally depends on the track, my timing, section of the track where I’m doing it.

I also put the Prime 2 through more grief with loops as the others as I’m mainly playing dance music on the others, yet I’ll play mega eclectic on the prime so lots of looping live drums etc then trying to beat match it in.

I think Engine DJ reanalysis should be the last step.

  1. Download track
  2. Run through MIK
  3. Tag in Lexicon
  4. Export to Engine DJ (unlock option in Lexicon, Auto Analysis option in Engine DJ)
  5. Do another Reanalysis in Engine DJ

As I said, I don’t like to use the Denon grid, I still think it has a way to go to stand up to Traktor for example. Lexicon grids are more consistent in my experience.

Surely the lead deck shouldn’t change until the previous track has finished? Never had to change the master deck in order to keep a loop synced!

It’s odd…

There is the risk of some shifting in beatgrids when converting between softwares.

This has been own experience.

How would this happen if the grids are locked?

It’s has nothing to do with locking tracks.

It is a issue with the mp3 encoder differences between softwares.

Eg software A is using Y Codec to handle compressed files

Whereas

Software B is using Z Codec

Even though audio will be outputted identically

Hmm ok, I will do some experiments today.

It doesn’t affect lossless files ie AIFF, FLAC

It affects compressed files eg mp3 and aac/m4a/mp4

Lexicon has a shift corrector but sometimes it’s still affects a handful of tracks
