I fully understand what midi in/out/thru does! I am not expecting to get midi to pass through to the midi out port - though apparently that is what I have to do through midi merging by the looks of things. My point here is that if I use a midi track on the OT, I am presumably controlling an external piece of gear. I am trying to get the parameters I set for each of these midi tracks to be send to the midi out port when I alter them with an external controller! So if I set a cc in a midi track to cc7, when I change this value on the OT, it will turn the volume up and down on my external gear - great! I can turn CC Direct Connect off and choose a midi channel and get my external controller to do this - great, but only on one midi track at a time. What if I want to alter 2 volumes at the same time? I can turn CC Direct Connect on and am still limited in what I can do simultaneously - I need to choose a track to do anything to it. I looked in the manual under "Using Octatrack as a Midi Control Center"and it is cool for some applications, but it seems to be designed for one synth connected to the midi in and out ports? Hardly a “midi control center”, but maybe it is a case of me asking for too much!

Anyway, rant over, solution in place - time to make some music!!
