PLEASE HELP Effects Routing

I have an audio only project of 15 tracks
Onlt three audio tracks work with effects (reverb etc) all the others dont?
If I add reverb or Delay etc nothing happens? In the Routing editor window (in the channel settings (when I press ‘e’) all the channels that will not respond to an effect have a straight vertical line - How do I rectify this please.


How do you “add reverb or delay”? Imsert FX? Send FX? What software are you using? Read the chapter about FX in the manual, then provide some useful imfo om what you are doing and trying to achieve?
