Converting Polymetric POLY Object to 4/4

Hi everyone!

I have this polymetric POLY object and i want to translate it into 4/4 for smoother editing in a notation software. I know of the method tree2ratio → mktree, but it seems to mess up my rhythmic proportions (see attachment).

I also found a way where I convert from POLY to MULTISEQ to POLY again, but doing it that way any rests are replaced by a tied note.

I’m wondering if there’s an alternative method of achieving what i want? Perhaps something that involves breaking a tuplet at the barline?

I hope I’ve explained myself clearly. Thank you in advance!

Dear zeracosaitam1

In your case i think the best is to run your poly in omquantify.
If you need an example, please do send the poly (or the patch).

Hey Karim! That would be great, i’ve never used quantification before, here’s the poly instance:

Thanks four your help!

Dear zeracosaitam1

In this case, quantification will work under some conditions:
it seems that you need to “Work” on it. I see why you want to use a 4/4 steady signature, but i think this is wrong ti use 4/4 meter all through. Structurally, since you use a chord, and trill alternating patterns it is good to have your chords starting a measure like in your original sketch. So, this will not fit in a 4/4 all through meter.
In quantification, you get to choose, to change meters, tempo and subdivision definition (precision). So in this case, i think you should “work” it out, meaning split your original poly, and quantify it by chunks, this is what i usually do.

I am sending you a raw bulk quantification, so you get an idea.

Here is a patch example.

PS: You can first split your poly with measures like 37/16 and modulate your tempo. Will let you know how.
