Well, generally speaking, you should be able to do this.  I just hooked up a TimeFactor to an H9 running the latest firmware, and the H9 was following the TimeFactor’s tempo correctly:

Could you try hooking up just your two H9s directly — configuring the first H9 to transmit MIDI Clock and the second H9 to receive MIDI Clock — to see if you can get the second H9 to follow the tempo of the first one?   

Thanks!  Will do.  To do this, does Global TEmpo need to be on or off?  This has been suggested but I did not want global tempo, only tempo changes where I send clock.
