I've had this problem before with [hid], apparently it's a hardware issue called 'debouncing', which is often ignored because it is often irrelevant (pushed is pushed, for game controllers, rather than a button-on/button-off signal used for most music systems). <br><br>You can deal with the problem in pure data by using a trigger, float and delay of one millisecond.

Hi list,<br>
<br>
recently I've been playing around with [hid] again and still have
the issue with double triggers on linux (see previous post <a href="http://www.mail-archive.com/pd-list%40iem.at/msg32170.html" target="_blank">here</a>).<br>
<br>
I've downloaded the latest version of
<a href="http://autobuild.puredata.info/auto-build/latest/Pd-0.43.1-extended-ubuntu-lucid-i386.deb" target="_blank">Pd-0.43.1-extended-ubuntu-lucid-i386.deb</a>
but I have the same problem with my existing Arch Linux installation
on my laptop as well.<br>
<br>
It works fine on Mac 10.6. The problem is that I basically get two
identical events for each key press and release, ie:<br>

print: key key_u 1<br>
print: key key_u 1<br>
print: key key_u 0<br>

Is anyone else having this problem?<br>
<br>
thanks<br>
