How to use external sequencer on mpc drum program

How to hear sounds from a drum program via Bluetooth MIDI with an iPad? I see the level moving and I can hear sounds when I switch to plug-in but not while in a drum program. I want the patterning app to sequence the mpc drum sounds.

Video example:

So I go this far but am unclear on what’s happening and is there a faster way to do this across all the pads?

It depends on where the Notes are in the Drum Program. We need more information on that Drum Program. Like...Is there a Sample on the Note/Pad thats being triggered

I just loaded a random kit that came with the mpc for an example. But each pad had a sound on it, kick snare clap etc
