I am having trouble layering short bow instruments with long bows. Suppose I layer the Cellos Grand Detache with the Cellos SusV. When the Grand Detache sound finishes, we clearly hear a gap between the two sounds. I guess there are some ways to fill this gap so that the sound looks like it just continues... I am trying some things here, but I was wondering if any of you have tips for that kind of things...? I am sure many of you have gone through this...

Thanks,
Martin
