Remember that the Vortex calls for a PASSIVE rocker pedal, not a 
standard CV pedal.  It uses a 3-connector jack (for TRS stereo 
plugs); one connector *outputs* 5v, one connector is ground, and one 
connector is the voltage return.  In order to use a CV source to run 
the Vortex, you'll need to make a cable that has a 1/4" TRS (stereo) 
plug at one end (Vortex side) and a 1/4" mono plug at the other (MOTM 
side).  Ths TRS plug will only have the ground and voltage return 
terminals connected to the cable, while the 5v output needs to be 
left unconnected.
