hello,
sorry for my late answer.
I have to annonce that Charles Verron has made (for la-kitchen.fr) a few abstractions made for the traitment of sensors.
they can be found here : http://www.la-kitchen.fr/download/kitchen_hardware/5_utilities/pure_data_abs...
this collection of abstraction where made to facilitated the use of sensor, assuming they send a constant rate data flow. you'll find debounce, trigger, filter etc...
dependency : zexy and cyclone

to stop multiple triggers when the value hovers around your trigger point, you might want to not register the next hit until the value has fallen below some lower threshhold. i've attached a patch that does this.
why did i do this? because i misread the question at first ;) .. but it's still useful.

Hi! I want to trigger drum samples with a P5 glove using midi.. My problem is probably simple to resolve but I had no luck for a week so here it is: I want to set a threshold value, letÂ’s say 75, so that greater than 75 only bangs once and can be retriggered only if it goes under threshold and back up. Most combination of objects that I tried banged more than once. Thanks for any hint!
hey, does that glove track position as well? personally, i always wanted to try that nintendo powerglove -> PC mod but i never got around to it...
try using at [> 75] -> [change] -> [sel 1]
see attached patch.
