Thanks for looking. The full code is below.
It works as given ie it starts as a 2 vs 3 polyrhythm.
You can speed it up by pressing D until the polyrhythm becomes 2 notes
However if I want to speed up by less than factor of 2 then it breaks.

About 11 lines from the end: the line
2 *=> Voice.multiplier;
if changed to
1.5 *=> Voice.multiplier;

Then it dies after a D and cpu shows 100%
This is debian linux.

There are one or two other enhancements also I would like
Can I make the clicks sound a little different from each other?
