Another user posted this:

Rather than using "Start Sending Timing Clock" as the midi command in MobileSheetsPro to send a tempo command to BeatBuddy, you are able to do the same with Control Change (CC) commands. The benefit of using CC is the tempo command is sent only once to BeatBuddy rather than continuously using the timing clock. This means during the song or when you exit the song, the tempo on the BeatBuddy can be changed manually. To set a tempo of 109bpm, the CC commands are CC106  0 and CC107  109.  Please refer to the BeatBuddy manual under Tempo Control for more information.

That user was controlling the tempo on the BeatBuddy using the "Start Sending Timing Clock" message in MobileSheets, but found it was better to set the tempo through control change messages.

Yes I know that solution, but you have to change command line each time the tempo is set on Mobile Sheet, twice...
Other devices are set by Master Midi 
It is what we need : Mobile Sheet have to be the Master for song change AND for tempo setup.

Depite "Accuracy excuse", why Midi sychro time do not work on Mobile Sheet ?

See below what AI said about BeatBuddy tempo control :
The BeatBuddy drum machine can be controlled with MIDI to change its tempo using INC/DEC messages or the MSB/LSB system. You can also use a MIDI clock to sync the BeatBuddy with other MIDI devices. 


INC/DEC messages 

• Adjust the tempo up or down by 1 BPM
  

MSB/LSB system 

• Skip directly to a specific tempo BPM
  
• Use the “NRPN Register” (Non-Registered Parameter Number) to control tempo
  

MIDI clock 

• A signal that is sent over MIDI to sync several devices together
  
• Allows you to set two or more MIDI devices to one tempo
