Hi guys! I don’t own an Octa but I read in the manual a chapter about using the Octa as DJ mixer. Apparently, there are two diff methods consisting in using a trhu machine or direct, while main diff being that thru machine can use the track effects.
It seems that both methods tho allow sampling and the used of master effects, but if the effect is BPM dependant, it needs to be adjusted manually or tapping the tempo…how does it affect sampling? Does sampling also need tap temping in order to be properly time stretch?
Can a pick up machine also be used instead of the two options proposed? Is there any way to use as a DJ mixer and the Octatrack grabs the tempo from the audio being input from de Cdjs?
Thanks in advance

DIR is affected by Master Fx (with track 8 set to Master Track).
No tempo detection (tap, midi clock slave or record a loop with Pickups).
Bpm fx follows set tempo.
Pickups can be used as monitoring, Flex machines too, playing the recording directly.

So having tracks 1 and 5 as trough machines, and any other track as pick up or flex, would that give it back the bpm from the “audio in” source and set it up as master tempo? Therefore master effects will have the master tempo and any sampling time stretch properly?
Would that also work even the pickup or flex machines are muted?
Thanks, and sorry for that many questions 
You can get bpm only with tap or recording with Pickups.
Yes, possible to record / set tempo with Pickups muted.
For fx, tap tempo may suffice, for sampling, I’d use pickups to set the tempo, more precise I think, especially if you use more than 1 bar.
Personally, for sampling duties, I think i’d use OT master tempo, and sync other gear to it. Possible to have a reference track sent to CUE for monitoring.

That’s very helpfull, thanks 
I understand that for sampling duties it is ideal to set up the octatrack as master, and slave the other instruments, but in this case, if using a cdjs or even decks, this option may not be possible and a work around may be needed for sampling the audio coming form de external outputs live.
I guess pickup will be helpfull for such a case, or even taping tempo, but pickup should be first option.

I found this an interesting read by the DJTT crew on how they mix their own creations with existing tracks for hybrid live-dj sets. Anybody tried this?
