stopping count~

I am trying to use poke~ to write a small amount of samples to a buffer~, say 50, I am using count~ to provide the sample index. What I would like to do is start count~ and once it reaches 50 for it to stop automatically. Any ideas as to an object that will work alongside count~ and send out a bang when a specific number is reached? Something a bit like select, but which works with signals. I tried feeding count~ into number~ and then hooking number~’s right outlet up to a select object looking out for a 50 but I guess the number stream is coming out way to fast for it register properly. Many thanks all!

will [< ~ 50] work for you? maybe the data would be coming way too fast again though... does your signal vector size affect the way this will work maybe?

Thanks for your reply mate, I did try [< ~50] but the act of converting the signal to number through number~ and then feeding it to a togedge to send out a bang to a stop message added a latency to the whole process. I just wish that count~ could have a loop on/off message so that is could simply perform the count once when banged.

what i meant was actually more like sending the output of [< ~ 50] to the input select part of selector, to turn the input on and off.. then passing through to poke~?

To do this with native objects you could just clip~ the output of count~ to the max number of samples you want so it can’t go over that number, and then use ==~ and edge~, the schedular latency of edge~ no longer an issue because your sample ramp has already stopped. Or you could have a look at Andrew Benson’s shot~ and/or cshot~ externals from the share pages which will achieve the same thing with less patching and less cpu load.

Actually this is slightly more efficient:
