Makoto:
Now how do I sync the two so the same algorithms are in the same memory position on both units?
I'm not sure what you mean by this. Do you mean that the algorithms aren't unlocked on both units? If so, if both are connected to H9 Control and you restore your purchases, it will unlock the algorithms on both. (You restore purchases by clicking on the Settings button in the bottom right hand corner of H9 Control and going to Restore Purchases.) Do you mean that you want the same presets in the same order on both units? If so, create the preset list you want in H9 Control, and use the "Save to pedal" function to transfer it over to both units.
