Sorry, 120.12 instead of 120.13 !
But it can help.
Yes, also I can get close by playing with loop position then in attr page playing with loop lenght.

Maybe this can be fixed in the next octatrack update.
Is there a (long) wishlist without comments ?
Of topic but I think most in that wish list are unreasoable or un do able wishes.
But this 
imo is necessary to be able to dj in almost perfect sync, and should be able to be implemented (as a guess, what do I know about code).
nothing to add, except 2 octatracks is (nice! butā¦) overkill for Djingā¦
Iāve been doing it with one OT the past six years.
Use studio mode and have deck A on main out, deck B on cue outs, straight into two channels on a line or dj mixer.

+1 for this. The gainstaging of tracks on the OT is awkward IMO.
When I originally got the OT, setting it up as a DJing system was the first thing I tried. Connected a reloop mixtour to it via bomebox, mapped basic controlsā¦ And utterly hated the experience. No xfader curve adjustments, setting trim/volfader/xfader behaviour while still using postfade fxs was a nightmareā¦ After setting it up to use an exteranl mixer, I found peace with it.
Prepping the songs is a chore though. I wish I could just convert TRAKTORās bpm grids and 1:1:1 markers to OT static slot metadata somehowā¦ Best ofcourse would be just to beatmatch manually, but thereās no properly implemented controls for doing that.

I have thought about Octatrack DJing as well, but Iāve noticed one big problem during my first sessions: the timetretch algorithm sounded so bad on low frequencies, that my track was ruined. Especially the bassline. Iāve stretched the track less then +1 BPM (for example from 125 BPM to 125.5 BPM) and the result was so bad. Iāve tried the same thing on Traktor and Ableton and their timestrech algorithm was way more transparent up to +10 BPM. Because of this I havenāt tried more DJ-OT-Setup. Can anyone confirm my experience?
Best,

I have to add something: in my setup I want to DJ with to Octatracks and pitch them manually ā¦
In that case, canāt you just disable timestretch altogether?
Shure, but how can I sync tracks, if both tracks have different BPMs ?
by pitching manually? I thought that was exactly what you wanted to do?
Hmm, but is this possible?
Example: Track A on OT 1 = 125 BPM ā¦ Track B on OT 2 = 130 BPM ā¦ Timestretch is off, so if I increase the Tempo on OT 1 up to 130 BPM the loaded Track wouldān stretch and plays out of sync with the OT sequencer. So the OT sequencer would cut my Track loop if I change the tempo ā¦ right, isnāt it?
Ok, 5 years and 9 months to be preciseā¦ 
(Got the OT in early march 2011)
Admittedly, i started out using just the master out and later switched to the mixer setup.
If timestretch is off, changing the tempo on the OT has no effect on the sample.
So yes, your loop would be out of time.

And thats exactly the bad thing ā¦ I need a simple oldschool pitch effect (like the rate knob) during the tempo change (like on turntables) but thats not part of the OT 
Indeed. I wrote to elektron about this many years ago and Iām not the only one, but they never implemented this, unfortunately.
Instead, we got pickup machinesā¦ oh well.
Because of this I thought I can mix only tracks with same BPMs 
Or I could implement special transition tricks to fill the BPM gap between both tracks ^^
Yes because of this I tend to mix tracks of the same tempo.
Alternatively you can make the timestretching behave more smoothly (less skipped bassdrums or weird sounding bass and such) by adjusting the pitch to fit the bpm change. Not perfect, as you get rounding errors and OT only allows 0.2 semitone increments.
The formula for the pitch difference in semitones ādā is:
d = ln (Tm/Ts) / 0.0577623
where āTmā is master tempo, āTsā is slave tempo, ālnā is log 2.
