i made it back. the kit shockingly worked pretty much as expected. there was one hang up. ipad ran out of free space backing up osmo videos, while we were staying at a hotel that didn’t have wifi. turns out there is a weird quirk with the files app where if you aren’t on wifi and try to access icloud drive with unsynced changes, it will just not work. so i couldn’t see how many videos i had backed up before it ran out of space and thus couldn’t tell what was safe to delete. and then the wifi never got fast enough again to catch up. so i had to buy a second micro SD card.
if i were to do it again i would probably cut the ipad (and its out-of-frame-above-but-in-retrospect-way-too-heavy-keyboard-and-external battery). phone would have worked as well 98% of the time (and did). would also probably replace the zoom with some kind of iphone mic accessory + card reader. i dreaded carrying around the zoom in my pocket, and when i wanted to get something specific, it takes like, 20-30 seconds to boot up. but i didn’t want to buy things that would have no function outside of this trip.
@spacelordmother yeah i had never heard of it either on this model. it’s such an arbitrary set of steps to set up, it really feels like i just found some hole in either apple’s or zoom’s planned obsolescence. i have not stress tested it super deeply simply because having a live mic in iOS is not super important to my workflow. but i have done it a couple of times now, and it seems to reliably work with the h4n (just set it up to monitor norns from the xlr inputs and that’s also working well so far). also @ThurberMingus asked about the specific model USB hub running into the CCK: it’s an old generation of the targus USB 4 hub. i think i got it on amazon like 10ish years ago, i couldn’t find the exact model on there anymore.
there’s one more gotcha i just found while double checking whether it still works: if you plug in the h4n while it’s turned off and try to connect it as an interface that way, it will crash and restart before ever making it to interface mode. you have to start the recorder normally, then plug it in, then launch the interface from the menu.
