lsdj as midi master sync

[Turboninja]

"LSDJ as MIDI Master Sync. Send Midi sync with LSDJ, LSDJ also sends a
Midi Note on message that corresponds to the song row number "
My arduinoboy works find in all slave mode I can control mgb
perfectly, lsdj, but I m now trying to find the way to sends note from
lsdj to my sampler, do you think it s possible? I can have a midi
clock in master mode in lsdj ( leds are blinkings) , but my machine
don t receive any signals.
Maybe it s not possible

Any idea?

Thanks
