# How to create a hierarchy of pulses

Hi,

I’d like to create a hierarchy of pulses analogous to how beats and their divisions behave in a measure. The way I have come up with is through a series of pulses whose frequencies are multiple of the frequency at which the firts beat of the measure spots.

In a simplified form:
LFPulse.ar(0.25) + LFPulse.ar(0.5) + LFPulse.ar(1) //Frequency of the measure + Frequency of half a measure + Frequency of quarter notes, and so on …

I have tried to do that with two alternative codes but it doesn’t seem to add properly the different layers -according with the output of .plot-. The version with Impulse is not working any better.

At the end it seems to be a matter of the picture:

Any tip on what to do to make it work?

``````// {Mix(LFPulse.ar(2**Array.series(6),0, 0.01))}.plot(0.35);
//{Mix(LFPulse.ar(2**Array.series(6),0, 0.01))}.plot(0.55);
//{Mix(LFPulse.ar(2**Array.series(6),0, 0.01))}.plot(0.75);
//{Mix(LFPulse.ar(2**Array.series(6),0, 0.01))}.plot(1.15);

//{Mix(Impulse.ar(2**Array.series(6)))}.plot;

// or, link to a GitHub page or a gist (https://gist.github.com)
``````

Hi again,

This seem to work properly and the graphs looks nice!

``````{Mix(LFPulse.ar(0.5*(2**Array.series(6)),0, 0.01*(2**Array.series(6))))}.plot(2)
``````

However, if anyone could explain what was wrong with the former try I would appreciate.

Thanks!
