In case anyone needs it , i found this
that i had done years ago [ should be correct ]
get a volt or so of power from the Rockman octopus midi unit
[ 8 funtion switches ] Cheers -Greg

Hey guys, I am trying to make a couple of loop boxes for my old Rockman Octopus. I hooked up my Octopus and checked a loop for output voltage when the loop is on and I get 4.2vdc from tip to ring on the stereo 1/4" output. I put the 4.2vdc across the coil of my relay (Fujitsu RY-5W-K) and it would not energize. I checked the relay on my trusty power supply and even at a little under 4v, it will energize. Any suggestions?

Red wire is the tip on the captive cord [ which goes to octopus unit ] white is the ring.
resister is 100k [ measured 92k IN circuit ] cap is 220 uf 16v .
Activating a loop on the octopus appears to put .6 volts from tip to ground , de-activating it
switches the .6 v to ring to ground

unless the wiring was different in older loops, i think i saw a mistake in the wiring at the input send return and output jacks on the drawing in this post, and the relay part number is different also than whats in my loops, so heres my drawing and notes, hope helps out you guys, if see any mistakes let me know,, thanks....steve
