No SF2's nor VSTs are required, although if you are currently using a version older than 1.3.0 and if the effects don't work on the older versions, then add the following effects on this list:
Calf Limiter LADSPA (turn input gain to 5.60687)
StereoEnhancer Effect (turn the knob all the way up)
Smooth Decimator (in HH in Beat/Bassline Editor, turn the resample rate to 19102.58)
Equalizer (don't need to readjust as much, there's also too many knobs for me to add anything here @_@ )
C* ChorusI (for 3rd square echo, located at Track 2 in Song-Editor)
