Hi there I am part of Sphere and have downloaded the Strings pack for Notion, downloaded the extension Bass Section Techniques which includes Col Legno, When I record some notes into a score through a Double Bass (Solo or Ensemble), I get playback which is fine, but I am unsure how to apply to Col Legno to the notes or the playback and I have no been able to find a tutorial for this or anything like that unless I have missed it in my search. Any help would be appreciated!
