I struggle connecting OP-Z and OP-1 using a simple USB-C to USB Mini cable. After plugging in the cable in sync mode the OP-1 briefly displays “EXT” for a few seconds, then “EXT” vanishes and no synchronization or midi exchange is happening between the two.
Without luck I tried all combinations of: order of plugging in; sync/master modes; selection of midi channels; midi in/out; clock in/out; de/activating charging on both devices; six different data&charge USB cables. - No connection or communication after the initial brief “EXT” display at all.
However, if I use a powered USB hub with the OP-Z as host in most cases the connection comes up and remains stable, “EXT” is continuously displayed on OP-1 in sync mode and both devices sync and exchange midi signals.
I tried two different OP-Z with the same results. OP-1 (#237) and OP-Z (1.2.14) both on latest firmware. Diagnostics on either device does not show any malfunction. Batteries on both devices don’t show abnormal dis/charging behaviour. Teenage Engineering wants the OP-1 sent in for diagnosis, but I am reluctant since that might take a long time, incur significant costs and there is no guarantee for success.
Any idea what might be the cause of the problem? Anybody experiencing the same?
I really would appreciate any help in solving this issue since the need of a powered USB hub sort of negates the portability of this great combination of instruments (or need to always carry a mobile power source in addition).
What was the outcome of this? I’ve not had success with MIDI syncing the OP-1 <> OP-Z, tried a couple of dongles but no success.
Has anyone found a cable that works without the need for an adapter? e.g this one?

I find this setup is very fussy about cables. I have a couple of short USB-C to mini USB cables that just don’t work, and a long one that always works perfectly. I can’t remember where the good one came from though.
