OP1 #243 Multiple audio interfaces output

Henlo there,

I am trying to aggregate devices to record live in logic.
In the Mac MIDI settings I’ve created an aggregated device to combine scarlet audio interface and the OP1. In the logic pro I can see signals are coming from both places just fine and I can record things simultaneously. But I can not directly monitor OP1 for some reason. As an output I am choosing the scarlet audio interfaces 1+2 output as usual. I can hear the sound after it’s been recorded though, so the problem is only for direct monitoring. Any suggestions?
Thank you!
