IMHO, adding an FX pedal to a synth rig is one of the easiest, simplest ways to upgrade that synth and give it a new echelon of dynamics.
I also have to say that the Zynthian is probably one of the best modules for this you can find, but that would definitely be a degree of complexity higher than the article tries to maintain. Still, an amazing FX box that really pushes the value of the F/OSS FX/DSP community (http://zynthian.org/)
