Yeah the wild things it does are due to the midi control messages detailed in OT manual ( midi appendix) 
Biggest issue I have with leaving them on is they eat up so many midi channels … which I’m always short on!
@CreepyPants , I know…
but this thread is about users are controlling/using OT, so I just shared my take - esp. now 1.40 has changed things.
not everyone one has access to a midi processor nor wants the complexity they bring (*) … so thought I’d share my simple approach - that requires no extras.
But as I said lots of way to use these beast together , none are the ‘right’ way - as we all have different needs and interests.
