I was asked to check a devices midi sync performance, I used the OT as the master because I know it has good sync timing both sync out or sync in.
In the test I hooked up the OT and the other device to my scope, and was able to see (and hear) what was happening and make the report.
Anyway after I synced the ARmk2 to the OT, the sync was absolutely bang on as expected, so I hooked them up to the scope to see a difference if any, there was no appreciable jitter, see the video below.
I zoom the timing window of the scope down to 2ms.
It is just another of the many reasons why I appreciate Elektron gear.
