Artesia Posted December 9, 2005 Report Posted December 9, 2005 Just bought a M-audio Trigger finger; a Midi drum trigger device with 16 pressure & velocity sensitive pads... sorry ..at £139 i couldn't resist ..and bypassed the diy urge. And yes, it works supprisigly well :)Will be shortly putting up some pictures of it up in various states of assembly & provide some information about it. Which may help some of you people out there looking to build drum triggers from scratch.A quck note about it, the drum triggers are based around a membrane holding 16 pressure sensitive resistors. Which vary their value in accordance with the pressure applied. ..i have to admit - i was expecting piezo pickups of some sort :)The resistive triggers are custom made by the company www.interlinkelectronics.com This is rather blatantly displayed on the membrane itself ! They make remote controls, interface devices & oem manifacture stuff for other companys ..check them out at the above link.Nothing new here; just the same thing everyone will get to see...Off with the covers.. and the main board plus membrane pad are visable.Top section of the unit, rubber trigger pad in place.The round domed rear side to the rubber pad give the impression that the best place to hit the trigger; is in the middle !Top side of the rubber..annnd.. The money shot...Here's the all important resistive trigger pad on closeup - with the branding clearly visable.
moogah Posted December 25, 2005 Report Posted December 25, 2005 Good work! the bottom of the pads being convex is interesting. I know that drum heads respond differently when struck on the sides, I wonder if that is a loose interpretation of this.
Steven_C Posted December 26, 2005 Report Posted December 26, 2005 This is interesting, I wonder if there are websites with more disassembly pictures like this?
Artesia Posted December 26, 2005 Author Report Posted December 26, 2005 no idea.. some exhist no doubt...Mind if theres any other things people would like to see the insides of... put up a request & i'll see if i can source one to screwdriver... & of course there are other people here who may not mind doing the same for everyone.Hey.. maybe there should be a section on this forum for posting midi Orientated Equipment Biopsies ? :)
