Midi data not triggering external synth

Firstly, apologies as I'm sure this sort of question gets on people's nerves but I just couldn't find an answer.

I have a Korg Prologue 8 synth connected to a Behringer UMC404HD audio interface which is connected to my MPC One via USB.

I can hear the audio from the Prologue 8 when pressing keys and the MPC records midi data in the track view. But on playback, the midi data is not triggering the Prologue. I can't for the life of me work out what the problems is!

Can anyone advise? Thanks

Sorted it. I didn't have the correct midi channel and midi port configured on the MPC. Doh!
