Thanks for your reply. But i didn´t figured out how to use the exp/vexp objects. But i got an i idea how to fix my problem. Maybe it´s not the convenient way how i used to do it. See the example in the attachement. Thx.

Thanks, Vichug. I´m on Win with Max 6. Are these externals available for Max6/Win7? I guess just for Mac or Max 5 on Win. Nevertheless thx.

[expr (($i1>0)*($i1>=20))*1 + (($i1>20)*($i1>=40))*2 + ($i1>40)*($i1>=60))*3]
|
[select 1 2 3]

or

[expr ($i1>0)*(($i1/20)+1)]
|
[select 1 2 3 4 5 6 7]

thank you, sorry for beeing late with my reply. This works fine, but is there an option that if a number occurs in these ranges just one bang is outputted and the other numbers in this range are getting ignored? I´m sorry for bother you again. I has had a look at the onebang objekt, but it doesn´s seems to work in this way.
