how is that list being generated? And how do you want to "play each group by itself"? I think we're missing a bit of the story here.

Normally I'd handle this in a loop; I'd start by feeding the list through [zl sub 0] to get the locations of the zeros, and then use zl slice to use those zeros as the demarcation.

You could also use

iter

sel 0:

right outlet sends non-zero numbers into [zl group]

left outlet bangs out [zl group]

the list is being read from a text file that is already prepared, and say I have a 4 frequencies like 220 440 650 330, I want to play them at the same time like a chord on a piano. The zeroes in the list would separate each "group". However each group has different number of frequencies like one might have 2 while another will have 4. So is there a way to play them like a chord except I don't know how many notes there will be exactly each time?

And how can I make sure each group separated by zeros doesn't mix with each other?

How are you going to trigger the next group if they are all coming from one long list? Is it going to be after a set interval or will you want a [button] to trigger the next one manually? Or something completely different?

I want a button to trigger the next one, but hopefully it can automatic like after each time a 0 is outputted,the button will trigger the next group to be played together

with this method :

you need to first feed teh list, then each bang you send to [zl queue] will give you one "group" that was separated by a 0. One after the other, and only once each group - if you want to resend everything from start you need to re send the list.

You can use poly~.
