There is only one effect generator, not one one per channel.
The effect source is set to individual, stereo pair, 1 to 8, 9 to 19. master or all inputs or tracks.
i.e. once you set up the effect and adjust dry takes levels of reverb, delay etc., you need to bounce the result to another take, (wet record), then reset and, (bounce), another dry take with effect to another take, (wet record), etc., till you build up a set of all new wet takes.
If that makes sense?.
