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).
try the USB-charge-disabled function on the OP-1?
It’s somewhere in the shift+album options, green knob on the USB screen I think?
Turn the OP-Z on last, after connecting the cable and switching on the OP-1. This works every time for me.
Thanks for your suggestions! Will try that power on procedure tonight.
I did experiment with the USB-charge-disabled function on the OP-1 (and on the OP-Z), that didn’t help.
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.
Keep trying. Once it works, it should work great.
Thanks mate. Do you have any pics of the cable that works for interest?!
I’ve found an adapter that works!
