Dear Steinberg,
could you please clarify this, because to me it is not understandable and not reproducible.
It was suggested, that the nice behavior of using cdc on unarmed tracks does still use the inserted plugs without bypassing them. This sounds very good in theory but seems ONLY to work on audio tracks.
When pressing the CDC-button on a instrument track - be it instrument track or instrument in the rack with a corresponding midi track, i disarm the midi-track or instrument track (or arm another track), the used inserts get bypassed - bad behavior. Unlike audio tracks, when doing that there, they DONT get bypassed, because the track is not armed- very good behavior
So the intended behavior ONLY seems to work for audio tracks.
So what does it mean, that “CDC acts on instrument tracks but not on the instruments themselves”? Are there any VST-Instruments that have latency themselves?
Summary: CDC behaves differently on audio and instrument tracks - unfortunately. It works very well on audio tracks, where when a track is not armed the inserts still stay active/not bypassed - which is highly desirable that way! On Instrument tracks inserts are always bypassed/switched off, even though the track is not armed. Wouldn’t it make sense to instrument tracks to behave nicely as audio tracks do with regard to the CDC function and arming? Is that technically difficult to do or just something that hasn’t been thought through yet?
maybe in the next version? should i file a issue or request or what would be the correct approach to enable that function? 
Kind regards
Steve
