<div dir="auto"><div>Hi Brian,</div><div dir="auto"><br></div><div dir="auto">I know, beautiful thing, a switch matrix. This works differently though. I've been able to identify the pinout of the plug and it carries two types of grounds, one for shield and one for power. It carries a +5v supply line and provides an Rx data input pin. So the original pedal for which this input was designed must carry some active electronics. I haven't yet nailed how they would gave done timing of the Rx channel. Anyone fancy a guess at what would have been in there?Ā </div><div dir="auto"><br></div><div dir="auto">RutgerĀ <br><br><div class="gmail_quote" dir="auto"><div dir="ltr">Op zo 15 jul. 2018 20:34 schreef <<a href="mailto:rsdio@audiobanshee.com">rsdio@audiobanshee.com</a>>:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">You only need 11 or 12 pins for a matrix to support a 30-note pedal board.

Anyone know which type of pedals could connect to this? Or what the control protocol is? I'm suspecting it's either a straight diode-matrix-scan input (but don't think there's enough lines to make up the required notes), or communication line to some kind of multiplexer or shift-register internal to the pedals. I have pedals from another brand here, with straight switch-outputs and I'd love to modify it to work with the Gem.<br>
