Midi Lans not working properly

I’m having problem recording midi lanes. If I open a new project at first it works fine. I have the transport set to new and stacked. Once the project is more complete, (additional midi on a track) when using midi lanes I will hear the first recording while recording the second. The original track stays highlighted and the new track is grayed out. When recording audio everything works fine. Anyone having a similar problem or know of a solution

Sadly, this is how Lanes work for MIDI. If you’re in Cycle Mode, it should work as you expect with “Stacked” chosen in transport. http://www.steinberg.net/forums/viewtopic.php?t=68319#p396716
