Moog Music Forum

As the Moog User Manuals suggest, using the powered CV inputs on most Moog equipment could lead to some interesting home-made controllers: light sensors, ribbons, pressure sensitive pads... has anyone had success building similar accessories to work with the powered TRS (three-ring) jacks? It sounds like Moog was thinking there could be a wide range of interfaces similar to the eowave eobody.

it wasnt made at my home...but i have a Effector 13 PEEP light sensor that i use with my foogers. Its Great Fun! put a strobe light by it and wave your hand or foot in front of and its like have a square wave lfo and a variable (sine,triangle, ramp how ever you move) shaped lfo running at the same time

Have you ever opened it up? What is inside? I saw those and imagine they are a 1/4" jack, a resistor and the front panel photoresistor, is that right? I'm wanting to make a pressure sensitive controller and think the innards may end up being the same.

heh thats exactly right! really simple but SO fun to use. only downside is you HAVE to use the fancy dual ringed chords. the cheap hosa patch chords dont work

Actually, Hosa does make affordable 3 foot long TRS patch cables. You can buy them single or spend $30 and get 8 of them. I use them for my homemade potentiometer bank.

duh.... i spent $30 on one....

I have (partially) built a CV LED lighting rig. 1 Control Processor (CP251 Styling) and four minimoog style LED banks with 10 lights each. Primitive circuitry, transistors, 9v Batteries. It was a project for college that got thrown by the wayside during the last few months. Still got a B+ though...
