I know about connections with the SEND/RETURN terminals when using with the EFX-1000, what can I do by connecting this unit's MIDI OUT terminals with the MIDI IN terminals on the EFX-1000?

This unit can convert the tempo information (BPM) into MIDI timing clocks and send this to the EFX-1000. Also, the EFX-1000 is equipped with a mode for applying effects in sync with the MIDI timing clocks input from external devices. By using these functions together, effects applied with the EFX-1000 can be operated with the tempo displayed on this unit's BPM counter.
