Specifically, do you insert the effect into the track directly, or do you create Aux's and then add the effect to those? (And I'm speaking of FX only, not processing such as GR or EQ). Personally, I much prefer to create Auggies, then insert the desired FX like Verb or Delay on that Aux, adjust the wet-dry ratio on the effect to full-wet, and then tap into that effect using an aux send from the track I want to effect. Reverb is probably the most common of effects, but delays and various modulators also work well in this type of architecture. Now...This preference of mine may just be a hold-over from my days working on consoles, when instead of using effect returns, I would use console channels to return an OB effect, which allowed further sculpting through the use of EQ, panning, levels, etc. What's your preference? FX inserted on the track level? Or sends to auxiliaries where the FX reside?
