I checked it a bit I think it’s ok. I’m using something like this in a Max js object so I can enter values from rotary controllers.

function euclid(steps, pulses) {
var r = new Array();
if (pulses > steps) { //test for input for sanity
post(”Error: too many pulses for steps, truncating to step number\n”);
for (i = 0; i = pulses) { //first case more pauses than pulses
per_pulse = Math.floor(pauses / pulses);
remainder = pauses % pulses;
for (i = 0; i < pulses; i++) {
r.push(1);
for (j = 0; j < per_pulse; j++) {
r.push(0);
}
if (i < remainder) {
r.push(0);

If you were playing a polyrhythm like 2 over 3 beats then one rhythm would have accents every other note and the other rhythm would have accents every third note.
