Creates one voice with a loop, and repeats (part of) the loop.
( maybe 2nd voice)
Very primitive aleatorics! Tone, duration, and volume are just parts of
the same pseudorandom number.
They will be strongly correlated, but it helps finding short loops.
Uses my functions, RAND, RMND, etc. and may be initialized via parameter, e.g.:
rand_987
and will output a score called total987.
