i recorded a video of this being its so easy to reproduce it
I have TOUCHOSC on my iPad connected to my macbook and have hot cues mapped from the iPad to Rekordbox dj obviously
if i use the iPad for a while and then try and use the CDJ ABC hot cues they almost now act as if slip mode is on even though its not, the iPad works great but the CDJ and keyboard buttons 1,2,3 or 6,7,8 are all messed up, When I press them they activate that hot cue in the track and then jump to a totally different one afterwards, for example I press and hold A, it plays from A but when i let A go it jumps to hot cue C
in the video everything is going smooth until about 30 seconds in when i use the iPad and then go to use the CDJ, you can see on the CDJ i hot A and when i let go it jumps to C, its pretty obvious and happens all the time
