Practice songs for MS4 learners

I can appreciate that it will take some time and effort to get fluent in note entry, shorts cuts etc, but I would also like to use some material that would demonstrate the use of various articulations and rhythm patterns so as to be able to put expression into my work and get away from the mechanical MIDI renderings and realise the true worth of MS4.
I could of course create simple bars for this but Im sure others must have been down this path so I dont want to reinvent the wheel. Brings me back to my Czerny youth.
