Not very random random notes

The 'random score' plugin seems to be capable of only generating a solo piano score in 3/4 time in A major. It also has a weird aversion to D-- the note does not appear in 5 of the 6 tests. Similarly, the rhythms are very similar: 1/8,1/8,1/4,1/8,1/8 or some variation of that, always with double eight notes broken up by a quarter note. I'm not sure if this is simply a weird limitation, but doubt it, because the 3/4 aspect and the complete lack of randomness in general seems like a bug.
