It’s possible that this is related. This is a behavior of elektron products.
You might be able to test by alternating the cc value which is sent back and forth between two different values on your locked trigs rather than trying to send the same value each time, or you could try the workaround mentioned above.
Unlikely but not impossible to imagine this could have something to do with it but if you’re already sending multiple different cc values then it’s probably not related.
