The problem is with the values you have chosen. You can pack the first 10 numbers individually but not the next 49 in groups of three because 49 isn’t divisible by 3, that’s why you’re missing "49" in your [coll]. The same goes for when you get to 256: there are values which didn’t make it into your [coll] because [zl group] was waiting to receive 20 numbers before outputting them as a list.
I don’t know how you’re using this [coll] but as an example changing your selection to [sel 0 10 49 99 149 269] and changing the message box under [sel 269] to "244" will include all the numbers from 1 to 512 in your [coll]. I hope this helps.
Thanks, it does explain now.I ve missed the relation between the [select] and [zl]
It s for a dynamic noise reduction patch.The index of the [coll] will then be assigned on a 40 something multifader reacting as a multiband noise gate.This patch is for setting the frequency band-groups in the buffer/FFT.
