It will ignore it unless you manually activate it, which can be done by pressing Enter/Yes. If record mode is enabled Enter/Yes will only re-activate a one-shot trig on the track you have selected.
Also if you want one-shot trig re-arming to be less dangerous (accidentally pressing Enter/Yes is easy) you can enable Func+Enter/Yes in the options menu.
If you are using the arranger Func-Enter/Yes will be automatically activated, as Enter/Yes is used for selecting patterns in arranger mode.
Your long drones will find a very happy home on the Octatrack!
