As I understand when A4 AK AR are set up with Overbridge it uses a totally different protocol than midi.
Is there any sync timing issues using Midi and OB along side each other.
Sequencing both overbridgeinstruments and external hardware synths?
Well, it works. I guess it depends on whether you thought there was Live/sync issues pre OB or not.
I was happy with what I got our of Live before OB came along. I don’t find that there is a huge difference now that OB has arrived to be honest other than it has removed a chunk of the cabling around my tiny man cave studio space.
My setup: AK/AR via OB. OT and MNM via midi. I have to also midi into the both AK and AR so that I can control program changes via OT as well as use the AK as a midi keyboard. This is an issue that appears to be limited to Win10 users (I didnt have to do this before upgrading).
Good to hear! Thank for the input.
I fully agree on the cabling. But I bet you got a bigger man cave than me. 3,5 square meter walkthrough closet 
In your setup, which machine is your master midi clock Ableton or OT?
Ableton is the master in my set up. I’m considering trying out the OT as the driver though but probably won’t bother - I never use pickups and I’m quite happy with how things are as is.
