Press and the HOTKNOB button and the RIGHT FSTW together for a few seconds to exit SYSTEM mode.
Now connect your MASTER H9's MIDI OUT to the MIDI IN of the SLAVE H9. Put the MASTER H9 in Tap Tempo MODE and try it out. You should see the tempos on both units sync up. Then put it in PRESETS mode to try a program change on the MASTER H9. You should see the SLAVE H9 change presets according to your map in the MASTER H9. The default RECEIVE CH is set to OMNI, so if you are having problems with the H9's not talking to each other, make sure their [RCV.CH] setting in the MIDI system settings are matching.
