ST3 sending MIDI to laptop to control video playback (in Resolume)

Hi everyone. Thanks to this community’s help we’re flying along in our ST improvements as a band. Thank you.

Next step is that we’d like to trigger video playback from ST3 using a laptop running Resolume. I have read through the manual and watched Scott’s YouTube tutorial but can’t quite figure it out to our needs. PREVIOISLY we do this from the SPDSX, which send a midi note straight to the laptop which triggers the video playback.

How do I accomplish this in ST3, running from an iPad, please? I gather we need a midi interface (recommendations welcome), and prefer to run a wired connection to the laptop. Please could someone advise:
(A) what hardware/cables I need between the usb c out of the iPad and the usb a in of the laptop
(B) how I set up the midi note send, different note per song, and always at 00:00.000

Thanks as ever
