Bc2000 (for the BCF2000 & BCR2000)

I posted a topic on this a long time ago, but I do not know a thing about editing sysex or 
really how to load a preset onto the bcf2000. I started to look for an editor, but couldn't find 
one for mac. 
Can anybody explain to an ignorant user like me how to at least START going about using 
this midi controller to send sysex messages to a Roland MKS-7? 
In the last post it was recommended to begin with the mks-50 patch but I do not know how 
to even go about this. (Also I've heard that perhaps they are not very similar to each other in 
this regard0
anyways, any dumbed down help would be GREATLY appreciated. In fact, I'm willing to paypal 
somebody $$ if they can create an MKS-7 preset for me! Seriously
