Hey guys,<br><br>I&#39;m interested in buying or building a 4X4 trigger pad.&nbsp; M-Audio&#39;s Trigger Finger looks nice, but I just want the pads.&nbsp; I have experience building circuits, but I&#39;m not an electrical engineer (but I am aerospace tho..).&nbsp; Any DIY projects would have to keep that in mind.&nbsp; Any suggestions?&nbsp;
