Connection problem

After 15 years of neglecting my urge to make music I am trying to get back into it.

At the heart of it all is an OP-1, additionally I have a Korg Electribe Sampler 2, a Volca Keys and an iPad on a Focusrite iTrack running Patterning as a drum machine and probably more.

I’d like to avoid using a computer.

So what do I need to get them all to sync? I’d like the OP-1 be the master with the others to follow. Would a iConnectMIDI4+ L do the trick?

Thanks for any help
