Tried USB C to USB A plug last night between the OP1 and OPZ. Keys played on op1 were received and lit the trigs. Start stop was in sync. OP1 glitched out on settings and was pretty unusable.
Has anyone actually gotten this to work well with an op-1 sync’d to the z by connecting the directly together via a usb c to a converter? I’m using the adapter suggested by TE.
Andddd it deleted all my patterns somewhere during the crashing when playing with midi.
I have the oplab and I’ve been able to sync both units pretty well. I like the op1 as master and using the Endless Sequencer to send and record melodies or beats to the opz. I can make more complex sequences on the op1 using the opz too. The only thing is that there is quite a lot of noise being generated from the op1 being connected to the oplab. I had to use high quality shielded cables and tweak the knobs on my mixer to make the noise almost non-existent. Overall its pretty cool using both devices in tandem. I still need to see how well sending midi cc from the opz will work.

Do you have OP-1’s USB charging turned off? That should help.
if u still can’t get rid of the noise, try a ground loop isolator.
worked for me. they are cheap

Second the good dr. I found no love with the charging option on both my op1s
Hi,
I am also trying to figure-out how to take the best out of both OP-Z & OP-1 together. After all:
- OP-Z is a great sequencer
- OP-1 is a great 4 tracks recorder (with of course its built-in synths)
So my idea would be that the OP-z would control the MIDI and the main music. While the OP-1 can allow more “live recording” while playing the OP-Z.
I used a USB-C to USB adapter such as this one : https://www.dhgate.com/product/type-c-to-usb-adapter-3-1-usb-c-thunderbolt/414257253.html
At first glance it worked : the OP-1 could send midi signals to the OP-Z. And in fact… vice-versa.
And when starting OP-Z sequence, the OP-1 “magically” plays the track from timecode 00:00
Great : it would then mean that both can play together whatever is on their tracks… and if I output both to a mixing table, then I can have them both making music…
However : after few seconds, the OP-1 seemed to interfere with the OP-Z :
- connection lost between the OP-Z and my ipad (for the UI)
- OP-Z sort-of frozen…
Then if disconnected the the OP-1, sometimes the OP-Z would come back to life by suddenly playing lots of notes and coming to normal tempo. very much like a buffer of midi codes that needed to flush.
I thought it could come from the fact that the OP-1 is trying to suck power for charging and thus puts the OP-Z in an unstable state. So I plugged a power source through the USB-C of the adapter I gave the link to. Unfortunately it didn’t change anything.
I do suspect that the midi signals are going in both directions and somehow saturates the midi interface.
Did anyone get more success ?

PS: OP-1 <--> OP-Z Sync Thread (Post updates #235 & 1.1.23) probably a better thread for this matter…
Firmware update might help…
Which one are you using as the master clock?
And how are you listening to them both? Are you feeding the OP-Z intomthe OP-1?
The OPZ is the master clock.
Then the outputs are put together through a small mixing table (“Maker Hart” brand).
It turns out that I managed to synchronize them both perfectly with a firmware update… BUT… now I have strong noise interference : https://www.youtube.com/watch?v=4JB33vgwxbA&t
Excellent. I tried using a Roland Go Mixer to mix the two together and it worked fine.
I need to look at the MIDI settings for both. Pressing Play on either device starts both of them right now.
You’re lucky…
Now, one can try another thing that really shows how much noise interference the OPZ adds to OP1 :
- plug the output of OPZ to the Mic Input of the OP1 (so that you can record the OPZ to an OP1 track), you will
- plug them together with midi (USB) so they synchronize with MIDI
- activate the line-in to hear the OPZ via OP1
Normally you should get a crazy interference of a high pitch noise, over the OPZ sound…
Is this related to the opz as usb host is charging the op1? There was a feature to turn of loading on the opz but I guess the other way around that it is not charging with connected USB.
You can turn off USB charging on both op-1 and op-z to help. On mine I still get some buzz. I bought a ground loop isolator off amazon and it sounds perfect.
If you route your audio from op-1 and op-z to a mixer instead of from the op-z to the op-1 you won’t get the buzz when the two are connected over USB.
Well, I wish you were right for all the mixers… on the video, I show that the mixer I have doesn’t prevent such a thing. I tried on a professional mixer and although the buzz is lower, it’s still there and to my opinion no acceptable.
I guess I will have to check for the loop isolator… USB one (people complained that the sound loop isolator deteriorates too much of the sound quality, removing frequencies…)
Sorry I didn’t watch the video. I am using the exact same mixer and don’t get that. It might be the cables you are using? I don’t have that usb to mini usb cable but I thought about buying it but have not because so far I have tried buying two different cables off amazon that said they could be used for data that don’t do anything. The straight through just usb-c, the apple usb-c adapter and the TE cables are the only USB cables I have had any success with.
Good to know ! Thanks
Could be the cables… I will try more.
Now, I suspect my OP1 is responsible. I bet it didn’t get properly shielded…
Final note : I think my issue on the buzz sound is resolved. And yes : I had to cancel the USB power on OP-1 and OP-Z (“Screen” button + E2 Note).
Now, looks like I can’t put the OP-Z back to USB powering… “Screen” button + E2 Note doesn’t seem to toggle it back… but it’s another story
