I've read it somewhere in Internet. piezo output is limited using zener diode (you want to do this anyway because next electronic components may get burned out). Then you can measure width of the impuse. Wider the impulse is, more "attack" you have. In midi terms drum attack becomes midi note on velocity parameter. > > I understand the concept and design roughly and I can move on by reading the > construction manual (refering to edrum's DIY guide), but at the moment I'm > looking for a quick way to build a trigger as I need it asap (and no $$ for > a real trigger kit/module). > _______________________________________________ > Linux-audio-dev mailing list > Linux-audio-dev@xxxxxxxxxxxxxxxxxxxx > http://lists.linuxaudio.org/mailman/listinfo/linux-audio-dev -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>
