X3: The midi-note will be playing if I play it from the middle?
Will I hear the sound of those notes?
 

You will not.  This is a behavior we often consider adding.

You definitely should add this. Studio One does it and it's really good. Maybe in X3c? 

+1 for me as well. It can really make a difference when working with horn arrangements and such.

Please Don't.., or if you do, at least make it an option...

T'would be a nice addition for us keyboard/midi types.

Would you let us know why you don't want it? 

I would like it added, but make it switchable behaviour per project.

Yeah, I agree. A few other DAWs have MIDI chase and it's a nice feature, although I have found that it doesn't always behave as intended when the synth part is arpeggiated, sequenced, or makes heavy use of sync'ed LFOs. So, if it ever is implemented, having the option to turn it off would be nice.

+1 - I would also love to have this.   As an option.
