As much as I would love “overbridge” functionnalities for the OT, this won’t happen nor a MK2 version, and I won’t hold a grudge at Elektron for that.
-
AR will be the main focus gear for the year coming (polishing the OS, adding synthesis machines, FX, sample functionnalities, sound packs, unlocking the hidden +drive feature, revealing the Michael Jackson moonwalking easter egg…)
-
Overbridge for A4/AK/AR to finish by the end of the year (with a new OS per hardware), VST dev, UI design…
-
Taking care of their new products shipment and support and so on…
I think Elektron HQ will be pretty busy.
What I wish for is a project/sample manager for the OT as Jon stated beeing hardware orientated doesn’t exclude a better communication with a computer. Well this would be really usefull to have an OT manager in this regard. And better for the workflow. I find it hard to believe there is so few samplers (to my knowledge) with official software manager since the MPC4000.
Not having Overbridge for the OT doesn’t undermine the beast (sure it would have been great to get 8in/8out via USB). But then it still is a powerfull hub for the other machines and get you creative away from computer.
Once Overbridge is out for A4/AR, it will open up routing possibilities, free ins and outs from the audio interface. Plug A4/AR via USB, OT via audio… OPTIONS… That is nothing to complain about.
My 2cents… 
PS : this is a hobbyist perspective.
I own a MD MK1, MM MK1, OT… Lurking for the A4/AR combo.
I didn’t jump on the MK2 wagon, sometime I regret not to, but have limited founds. What I don’t regret is getting the OT instead.
