Hi
First thing you can check is the Auto Channel instrument in the Reaktor ensemble. If you scroll down you should see it. The instrument only have 1 button called “track down”
Now make sure this instrument is connect to your midi output and on channel 11[ in the Instrument properties ]
Then select a scene you want to write on the Octatrack
Press T1 [track 1] on the OT
Hold down “scene A” on the OT and press the “write button”
you should see the red LED move down to track 2 etc
Once it is on track 8 all the parameters affected by randomization should be written to the scene
[Note that only parameters selected for randomization will be written. If you don’t want to write some of them just uncheck the red buttons next to the cells]
I hope it helps and that you can get it working
Most likely the problem comes from the “Auto Channel” instrument, just make sure it is connected to your midi device
