Saw the title and was curious as I've wrestled so much with my beloved Tempest. . . but this is a new issue to me! What Tempest OS are you running? Did you ask DSI support? Would love Carson's take on this. . . A ta sante!
I have midi sync issues with the tempest going into logic and I'm always dragging the recorded track back a few ticks like you experienced. Perhaps it's an internal latency in the Tempest from midi to triggered sound?
