Ok member Morbid got me thinking the other day in this post.
http://forum.fractalaudio.com/threads/diy-wah-vol-expression-pedal.109094/
Well here it is and it works like a charm with my mfc, and I am hoping it will also work with the AX-8 that I am waiting for invite on, as are many others.
The whole reason and purpose for this mod is to have 2 ext controllers operated by one control pedal to save room, and to save cpu( by not having to use mixer block or volume blocks to make this happen) I have rewired the SP-1 so that the switch now switches the variable pot connections between the 2 trs jacks, instead of the pot on 1 trs and the switch on the other. So now this is 2 expression outputs but only one works at a time, when you switch the toe switch the 1st trs jack is left at toe down and the second is variable, and after the switch is pressed again the 2nd trs is held at toe down and the 1st one is variable again(much like the expression pedal on the pod hd500). I am now already thinking about modifying my other SP-1 to have this feature but with the switch at the heel. then I would use one for volume and wah, and the other for things like the formant or delay mix, things that you want to start from the heel.
Now I am not an engineer and do not know much about electronics( I am a heavy diesel truck mechanic by day and a guitar nut by night!) so don't laugh, don't tell me how bad my wire connections look, Because I already know! But I am posting pictures here and maybe some crafts men that are good at this stuff can improve upon it.
Ok I started with an SP-1 which was already modified to have the jacks on the right side so wires would not be on the out side on my mfc rig( so when mine doesn't look like yours this is why). The only additional supplies needed a few small pieces of wire. every thing else is already there. so here are the pictures!
This is my board
This is the SP-1
this is the before
the after!!!!
