I want to use it with my Lyra-8 which needs a gate pulse, too. I am trying to find a circuit that would make a gate pulse to accompany the cv of the EHX . Ideally small enough to fit in a box that could be considered "inline" and battery powered. <o:p></o:p></p></div><div><p class=MsoNormal>Sent from <a href="http://www.typeapp.com/r?b=14068">TypeApp</a> <o:p></o:p></p></div><div><blockquote style='border:none;border-left:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;margin-left:4.8pt;margin-right:0in'><pre><o:p> </o:p></pre></blockquote></div></div></div></body></html>
