oh nice. ok so I checked the settings:
OP-Z via USB to Logic Pro, preferences to OP-Z Audio in and Out and thought we can route the Audio into a DAW and straight via USB out and monitored by OP-Z but the Headphone out on the Z is plain Dry, checked all possible connections with a trrs splitter and the manual headset mode and a straight line out of the macbook into the Z but even that won’t record…just a big HIT but no sound at all. as described above.
now I wish TE would allow the Headphone out of the OP-Z to act as a Monitor Interface for USB Audio. like having a Monitor function regardless of the Sample Editors Monitoring.
at least that was my initial thought on that, routing everything via USB, enable the Headset Mode manually and let this happen as monitoring feature but nope. not yet I think.
