Splitting MC8 midi out to go to 3 devices

Can I use a simple passive 5pin midi splitter cable to send my midi out to 3 different devices (boss RC-500, hx stomp and Kemper profiler)? Or will there be a power/current issue?
( I tried different Midi through setups but they don’t work → expression pedal signal issues or latency with looper commands depending on the device order)

I use a 1 in/4 out splitter and it seems to work fine.
