[sgroup] S760 remote control with MIDI or rc100 input?

Hello, I'd like to remote control my s760's front panel buttons. Just like the rc100 does, but using midi. The best would be that some sysex could control them, but i wasn't able to find these commands on the sysex chart. Then, i was wandering what kind of signal emits the rc100 (that i don't own), so i could eventually build a converter that will translate from midi to rc100 input on the s760. I'm far from an electronic expert but i can use a solder iron... Simply using the rc100 will not do it for me, as i want to be able to record the remotely pushed buttons on a midi sequencer... Any idea is welcome Many thanks, Boris
