I made an editor of sorts using TouchOSC and an iPad – although I think TouchOSC will is available for non-iOS devices as well. The companion desktop app allows you to create and assign any number of midi-cc outputs. More info here: http://hexler.net/software/touchosc

The most time consuming part was configuring unique cc's for the controls in my TimeFactor and PitchFactor. (This could be a very useful feature in a genuine software editor librarian) I realize I could have used separate midi channels, but chose not to.

I essentially designed the knobs/sliders as a performance interface, but realized it could be used more effectively as an editing interface by saving a preset once an interesting sound had been created. I put 2 Factor pedals on one page, but could also have separated them onto separate pages within TouchOsc.
