Why no effect?
Some RTs have reverb don't they? Do you know for sure that RTs don't have any EQ or compression? Don't some guitars have overdrive?
Presumably because it's supposed to reflect "classical" music
But of course even classical music uses effect touches like reverb, so I took this restriction to mean something like additional vst audio effects. You are just never going to make anything sound natural or "realistic" without reverb.
Edit: I'm still wrapping my head around where "food" comes into the picture!
