AX-7 Patch Selection Help

[Jovix]

Hey guys, I recently joined a local band as the keyboardist/ backup vocalist. I've had an AX-7 for a while now that I've used to play stuff on my computers, but now I'm looking to use it during our performances. [it's come in handy a few times during practices when the drumset is out of commission and the drummer has to play on my keyboard, while I'll play keyboard parts with the AX-7.] I have a Roland Juno-G that functions as my sound engine, but I am at a loss on how to select patches with the AX-7. More specifically, how to select patches outside of the General Midi ones the AX-7 is preprogrammed with. If I select a patch on the Juno-G, the AX-7 will play it fine, but as soon as the patch is changed on the AX-7, the Juno will receive the patch change, and select the cheesy sounding Midi stuff. I've searched for a while now, but documentation on this thing is hard to come by, and when you do, it's all very basic stuff.

So, I guess what it boils down to is how can I configure my AX-7 so that I can specify a sound font (I think is the correct term) on the Juno-G to a certain patch on my AX-7.

(As an aside, I have a basic understanding of MIDI, and can identify some things such as note velocity, pitch, and volume, by other concepts not so much.) Any help would be greatly appreciated, whether it is a firsthand account, or if you could point me in the right direction. Thanks in advance guys.
