Bc2000 (for the BCF2000 & BCR2000)

can the bcr2000 send sysex to older roland synths, specifically the
mks-7 (basically a juno106? If yes, does a pre-programmed patch exist
(juno106 patches also work)? 

Is it relatively easy to program the sysex patch myself? I have a
chart of the mks-7's parameters and related sysex messages. 

Thanks guys!
