Hi, I've created a remote script for my APC40 that incorporates some of Push's sequencing capabilities (drum and automation sequencing). It goes by the imposing name APC400000 and can be downloaded here; documentation can also be found at this link. This is actually an adaption of Will Marshall's Push sequencer script for the APC40 Mk2, so many, many thanks to him for his great work.
(There is also a Max for Live device that goes with the script, though not at all required: APC Device Navigation.)
If anyone wants to try and extend this script in some way, that would be absolutely fantastic! It's all on github.
Hoping you might find this useful,
Martin
