UMH - 21 with BOSS GT-1 MIDI commands

How I know from DOREMIDI site The GT-1 understand SysEx messages through UMH-21 .

For send SysEx need to know : Device ID , Model ID , Address Map .

Can You help me with this, please.

Other thing I found in Internet , some MIDI controllers use CC messages to control Boss GT-1 .

My GT-1 at the moment can receive MIDI Clock massage. It has a MIDI sign on its display instead BPM .
