# Accum - and I'm lost :-)

Accum.omp (8.9 KB) EDIT: The example from the manual is now working. My fault. I’ve added the patches.
Question: How can I extract the numbers from the list in Listener. (Sorry for this rudimentary question.)

Hi, I’ve programmed the accumulation-example in this link, and as output I only get the last number not the whole list represented in the example.
https://support.ircam.fr/docs/om/om6-manual/co/Acum.html

What I’m trying to achieve by modifying the example is the following:

1. Taking for example the following list (4 3 3 5 1)
2. I’m looking for this procedure: 0+4=4+3=7+3=10+5=15+1=16 et cetera.

Hi Dagfinn, check #'dx->x

Hi Anders, thanks a lot!

Hvorfor gjøre det enkelt når en kan gjøre det militært.

Ta da! Thanks again! This is perfect.

Dear Dagfinn,

Hi again. Yes Anders is right, what you were looking for is dx->x, a classical way to compute “onsets”.

However jsut in case you want to know how you should program this in a loop (not so difficult, you were nearly there…):

Should just have to collect your accumulations (like above)…

Dear Karim, thanks a lot, I’ve modified the patches now. Cool. I really need to be familiar with the Loop-functions in Open Music. Some of my patches are really not elegant and very home made.
I tend to think that the most complex solution has to be the best one.
To my “defence” I had on the sketch written “intervall I mellom dx-> eller x->dx.” But until now - over 20 years - I’ve only used those functions for pitch, so I didn’t test it…

Best, Dagfinn
