Internal Blocks Midi communication

I’m pretty new to Blocks and coding but would like to use a Lightpad M block as a a standalone midi effects unit, starting simply as a delay and then moving onto to an arp or triggered step-sequencer. I’ve had a look at some sample littlefoot files, including one for a step sequencer and have had some initial success with it responding to midi note information from an external keyboard. I’d ideally like to be able to use a Seaboard Block as the midi note generator but haven’t had any luck so far with the code which works with external midi.
Can (Seaboard) blocks send midi messages internally to other blocks and if not is there an alternative internal protocol I can use instead so the Lightpad is able to respond to Seaboard note/touch events?
