Virus B Single Dump

[roboticefx]

Hey all, I've recently picked up a used Virus B. It's awesome and I've been buried in it and the manual nonstop. One thing that I'm having trouble with, is dumping a single patch. I'm using the .pdf documentation and it says how to set everything up, such as: CTRL, then under MIDI DUMP TX select SingleBuff (for example if I wanted to dump the contents of the edited patch) or SingleBankA to dump the contents of all bank A patches.

So, my question is how do I actually initiate the transfer after this is set? I guess I'm looking for a "send" button or an "enter" button on the Virus? I've looked in the manual and on the forums but can't find anything, so it's probably obvious and I'm just missing it...
