For what it’s worth I’m 48 hours into OT having come from a DT, DN and AK setup. I am by no means a power user on the AK - I just use it for poly mode mainly - but I’m fully versed in the Digi world and have started to run into the limitations. Hence OT. There are moments when learning the OT when no sound comes out at all and the behaviour is baffling, but it’s all user error. I usually start again when I get in a mess and refer to the manual all the time for bits I know the OT can do but for some reason isn’t working for me. However, after those two solid days I have a good set up going with OT, DT and DN all synced up and triggered from the OT as master. Also got the hang of recorder trigs and the Midi arp - amazing stuff. So, yes, it is mind boggling at times, but that’s because it can do so much. Just stick with it. Baby steps with a clear idea in mind each time you switch it on.
Also, regarding using the DAW as a tape recorder, don’t forget that your DT can use Overbridge and take outs from the OT into the inputs (then mute/solo tracks for each run to have separate stems as such). Not sure if DT monoises the inputs though - I’ll probably go to the DN or AK if that’s the case. Good luck!
