Problem 1: Can't merge SD cards

If you're a DJ, imagine the following scenario.

You're practicing for an upcoming performance, setting up your cue and loop points ahead of time with a CDJ-1000 MK3s with SD cards loaded in them.

Assuming you have two CDJs, you will alternate which CDJ is playing the current track as you mix (A then B then A and so on). Naturally half the cue points will end up on A's SD card, and half on B's.

Unfortunately there is no tool, commercial or free/open source, for merging/synchronising CDJ-1000 MK3 SD cards. So during your performance, you must constantly swap SD cards between CDJs to ensure the correct cue points are loaded.

Or, if you were smart, you only used one SD card when you set up your cue points (passing it back and forth between CDJs so it recorded all cue points), then manually cloned it using an SD card reader so you have a pair. But that's a pain.

Problem 2: No compatibility with other CDJs

At time of writing, the only other device or software capable of reading CDJ-1000 MK3 cue/loop points is the new CDJ-900/2000s. But it is a one-way compatibility; cue/loop points saved on a CDJ-900/2000 cannot be read on a CDJ-1000 MK3. Clearly there is some need for a tool to export CDJ-1000 MK3 cue points, at least into a human readable format so they can be re-entered (or loaded automatically) on other devices/software (e.g. Serato).

Note Pioneer have [stated in an email](Pioneer Email) that they have no plans to release the file format used by CDJ-1000 MK3s. So it falls to us, the community, to create together a tool for ourselves.
