[sgroup] s760 Panel or mouse MIDI control?

Hello, Does anyone knows if it is possible to control the front panel buttons or the mouse clics & movements of the Roland s760 with MIDI? I mean: like using a rc-100 remote but with Midi instead. What kind of information does the rc-100 transmit using its specific cable? Midi? I heard that the s330 transmits midi sysex informations while it is controlled by the mouse and is able to receive this midi back & recognize it (i haven't got a s330 myself to try it though), so maybe there's an hidden sysex implementation of these controls in the s760 too? I tried looking at the s760 sysex documentation (thanks again to Ingo) & didn't found anything, but maybe i'm just blind... ...any idea?
