Rikki, my guess is that if you are not using Reverb or Chorus you would find significant improvements in the sound by adding such effects. The PSR and others automatically add effects and are present all the time (unless you change them). In forte you can add VST/DX effects on the effects part of each bus. The instruments are located on the first section of each bus followed by the effects. I feel this is a very important subject to master. It will improve your sound. I don't use alot of effects but do use some amount even on my very expensive melody/lead voices.
