You _really_ don't want to abuse square wave and patch time like this; floating point math isn't exact, so subtle rounding errors can make edge cases pass or fail contrary to what you expect. That's not at play here, but in general this is dodgy territory. With 1 iteration, Iterator Variables' position is always 0.5. With 2 iterations, position will be 0 and 1. With 3, it will be 0, 0.5, 1. A square wave from LFO with a period of 1 will have an output of 1 at 0 and 1 (but not 0.999). In fact, with a period of 1, _all_ integer times will output 1 (until rounding kicks in at larger times). It remains 1 for the first half of the phase [0-0.5), and 0 for the second half [0.5-1.0) -- note the braces, they're important ( http://en.wikipedia.org/wiki/Bracket_(mathematics)#Intervals ) Anyway, I used your composition as a skeleton, and fleshed it out to graph LFO operations over an iteration interval (plotting X and Y as Iteration Position and LFO output respectively), and don't see anything unusual -- just the LFO outputting 1 at both 0 and 1, which could seem unusual but is in fact mathematically sound.
