Automating Buses: Tests and Conclusions

I'm investigating how to automate buses and I've found a working way.
I'm sharing screenshots and an example file.

I want to share my doubts and conclusions:

1_
Despite deactivating Control from options, it seems that if they are internal sends from the open instance, the MMCs continue to work.

2_
In my configuration we don't avoid the coupling (reflow, loop) of events. Simply because controls not preassigned in the midi standard are assigned, these reflows seem to have no consequences.

3_
I think it would be relatively easy to avoid the reflow with a conditional, maybe I'm wrong. It would consist of adding a property that would enable or disable the reception of MMCs. When we want to create a bus to automate buses or tracks through midi clip, we simply deactivate the box and the reflow is avoided.

The Bus faders are the only ones that refuse to receive MCC data, I don't know why.
