Ok, so here's what i found.I tried the scheme that was suggested for the psycho lfo and had no luck,i don't even think certain parts of the module were getting enough power because it wasn't working at all after making those changes(i'm running this on 12v supply).I tried some different values and still nothing so i basically decided i'd deal with a little noise on the rail instead of a module that doesn't work, but i left the 120uf electro's in place just to see and sure enough the bleed is gone on the rails.
Thanks so much for everyone's help on this!
