select and float - why can't I bang?!?

[register]

Hey, I'm REALLY sorry for multiple posts with me at my knees for help but... I think I have my random sample machine sorted except for one tiny weeny problem...



I am using groove~ right outlet to go an snapshot~ object, and monitoring how far through the sample playing is (it goes from 0 to 1). I want to use a select object, so that when the sample gets to the end (1), it triggers a bang. I've tried loads of stuff, but the select won't trigger the bang. The sel / bang will trigger, however, if I drag the mouse on the float number box, however, when running through the audio sample, no trouble occurs.



Like I say, I'm really sorry to keep posting about my incompetence, but your help would be greatly appreciated.

Thanks

Tom

No sweat, Tom (register). I think your problem is simply that the select object never actually receives the exact "1" value that is sent from the right outlet of groove~. This is because of it's sampling interval. The sample it happens to take unfortunately is not the one you're needing. Try instead using an ==~ object to test for exact equality to 1.0. Then pass the output of the ==~ object to edge~. The left outlet of edge~ will bang every time the end of the sample has been reached and the exact 1.0 passes from the right outlet of groove~.

Hi Register,



You necessary need to use the "replace" message instead of "read". It will automatically resize your buffer~.
