They sent me a beta version but unfortunately it didn’t help for me.
I am still getting noise (increases with the amount of button lights on) when I connect Hermod (in my Palette) to my main case (IJ 7U). Haven’t tried with any USB connections though.
I suspect it has something to do with the power supplies or even just the wiring in my apartment. Somebody said on the Squarp forum that they were having the same problem using two IJ cases together, and they fixed it by swapping out the PSU on their smaller 4U case:
I was having a hideous high pitched sound when connecting two different cases together using Hermod.
It took me a minute to track down the problem, and it turned out to be the stock power supply which ships with the Intellijel 4U cases.
MeanWell GSM60A15-P1J
15v - 4A - 60W
When I disconnect from the main case, the noise was gone.
I corrected this swapping the GSM60A with a second PSU
MeanWell GSM90A15-P1M
15V - 6A - 90W
I may try that next but have been looking for an alternate solution in the meantime.
All that said, if anyone wants to try the beta firmware Squarp sent me for themselves, shoot me a message! I’m not sure if they want it out in public yet and obviously no guarantees on my end, but it could be worth a shot.
