Hi guys, I meant the Midihub pipe, but I created myself and it’s working 
@sezare56 the problem with pc sent from midi tracks is that I actually need to send a pc when changing parts. This way (midi>sync page pc) it sends cc61 with every pattern change, so I don’t need to actually configure another program for every part. I guess…
Yes. You can send any midi message to do so. Maybe I’d use a note.
if you change pattern without part change the CCs sent by CC request should be the same, hence no need to send them. Isn’t it ?
Ok, this is quite embarrassing: I was going to check the Midihub pipe again and I hadn’t saved it. However it’s working.
And I’ve just realized… all this cc61 stuff I’ve been two days reading about… only applies to AUDIO CC right? 
I’m only interested in MIDI Tracks CC, which seems to update in both ways without doing any extra job
Am I right? 
Now that FW2.0 is there - a switch can pull the CC61=0 i.e values from the OT, is that only needed when switching parts - i assumed i need to update the controller, when i control the OT via manual interaction.
Or do i need to update the EC6 also when i change groups on the EC4? Remapping a Note to CC61=0 is for sure a handy idea too.
