I used a standard pedal with the VoiceWorks plus to switch (on/off harmony) for years connecting via a 1/4" stereo (TRS) plug to two mono sockets splitter, connecting the pedal to the unit as switch 1. I just upgraded to the VoiceLive Rack and used the same hookup and it works fine. Keep in mind you must change the unit's setup for switch one to do harmony (or whatever else you want, as it defaults to stepping patches).
I'd like the momentary switch capability, but I've gotten so used to the on/off that its hardly a problem. I use a three pedal unit under my keyboard and use the middle pedal for the harmony.
You can make your own splitter with connectors/wire from Radio Shack or Google shop for them. You can find the schematics kindly provided by TC Helicon at:
