I think this is one of the downsides of studio one ( mystery ) midi protocol
When using regular a midi track , there is hardly any strain on the cpu .
But when using a midi capable vst to send midi notes ( in my case audio realism abl3 ) to hardware , the cpu rises with 5 to 10 %
I have tried this in hosts like reaper and renoise , only studio one adds more cpu cycles
Could this be because of converting their (look mom no midi ) protocol to regular midi ?
