Sending sync to Boss DB-90

Hey all. I am trying to slave a DB-90 to send a click to my live drummer. All my tests with the MPC->DB-90 so far have failed.
I tested the midi cable and DB-90 by slaving it to Reaper successfully. I do not want a laptop on stage.
The DB-90 is quirky but it does sync.
Any assistance very much appreciated! TIA.

My current MPC Midi/Sync settings:

Output Ports: MPC Sync, Track
Remote: Track
Enable Midi Ports when discovered
Midi Control Mode Output: MPC

SEND: Midi Clock
SEND MMC: check
MTC Frame Rate: 30 Drop
Start Time: 0:0:0:0
Filter 'All Notes Off' CC: No
Program Change: Off
