Senario…

MIDI Controller (sends primarily CC and program change events) connected to in on H9 One.  H9 One out connected to H9 Two.  Tap Tempo switch plugged into EXP on H9 One.

Desire..

Use H9 One as a master midi time clock to H9 Two.  MIDI controller can send CC and program change to both H9’s. In effect, H9 one has somewhat of a merge feature..

Issue…

When H9 One is set as master midi time clock, and H9 Two is set to slave, tap tempo works to both devices, but the MIDI Controller changes are no longer recognized. When H9 One is set as a slave, it and H9 Two recieve midi data from the midi controller, and takes tap tempo – but does not send midi time clock to downstream H9 Two. 

It looks like this one is taken care of with the new crushstation midi merge for time clock….
