Bang on the first time, not on the second.

February 23, 2011 | 9:07 pm

I’m looking for an object or abstraction that will sequentially receive integers and produce a bang only at the first occurrence of that value. Repeated values should not produce a bang. I first thought this would be possible using zl or change, but I couldn’t figure it out.

The idea is to track the first occurrences of numbers 1 to 44 and ignore any repetitions.

thanks for any help,

I wonder could you put the numbers in a coll and then remove them when they are seen. Don’t know really but I guess I’d try that.

Hi, did you check the "change" object? It seems that the object provides what you need.

have a look at the "histo" object as well.

I have a similar question. I basically need a change object that will output a bang if the numbers DO match, so my patcher can try again with a new number.
I’m kinda surprised the change object doesn’t do that.

this is not so elegant, clumsily depending upon R->L

or…there are many ways to skin this cat.

Thank you for all your great suggestions. I went with Vanille and MIT’s suggestion to use histo. Works like a dream and very simple.

Thanks David.
I like skinning a cat with an if…then statement.
If the cat is skinned randomly while nobody is watching then the cat is both skinned and unskinned at the same time.
There are no objects for that.
