Hey Dinky,
You are going to need a USB to midi device.
USB on midi controlers is still fairly new to the midi world. there are several boxes that exist to make the conversion from pc to non-usb midi controlers:

(I personally use the last link)
While I think a good argument could be made that a midi controller geared PRIMARILY to a PC based VJ application like resolume SHOULD HAVE TO ship with usb as a standard feature, this is the first midi hardware of it's kind.
(for pc's anyway since the edirol/motion dive controler looks mostly useless and the livid controller is for mac:

A little flexability should be given to the company bulding the hardware.
so think of it as getting the controller before they are finished with it... not having to wait for the usb feature to be completed and still be able to use the controller.
As long as they keep the price low on the usb add-on I will be satisified. I don't want them making money on the add on.. I DO want them to make money on the controller.
If you don't have a midi-to-usb device already, than don't order the unit till it ships with a usb add-on option. It will not do you any good and you will have to waste money buying one of the above midi-to-usb devices, if you plan on purchasing the usb add-on when it becomes available.
