<P>Does anybody have schematics of an easy way to send</P>
<P>power using the 2 MIDI pins in a 5 pins cable ?</P>
<P>I don't want to use any of the 3 remaining wires of the cable</P>
<P>for universal use on ANY MIDI cables..</P>
<P>I know this company uses that technology:</P>

<P>but I can't find any circuit ideas that uses it..</P>
<P>I know I'll need some kind of charge pump design to get something like 5
volts</P>
<P>out of the MIDI (idle or in use) signal.</P>
<P>Any clues ?</P>
