G-Major + Viscount Px3000

Hi Guys

This's my 1st post here. To control my rack rig I use a Viscount Px3000 midi controller. I've no problem using it for patch selecting but I'm looking to use it to send #CC to the G-Major (to on/off single effect blocks into the same patch). Unfortunately I don't know how to set the Px3000 to do that or IF it can send #CC. I'm not able to find any user manual on internet (and it looks like you cannot contact Viscount), so I'm asking if anyone of you uses or used it or knows how and if about it.

Thanks
