Lelio, personally I would quit the sy77 sequencer and commit to the triton. Or at least make one the master. You will definitely find more flexiblility and visual with the triton. It's possible you can run into time off-set problems syncing the two sequencer or maybe you want to do tempo changes throughout the song. You can turn off the Rx (for the appropriate channel) on either synth or create layers with the both of them. Consider using computer software and a MIDI interface in the near future. You can get more out of your boards using all 16 MIDI channels.
