i'm trying to send midi clock out of my 1680 to the TD10 and the 660 to sync up while recording. I also want to trigger patterns on the 660 using one of the pd's. I have achieved midi sync but the td10 and 660 start and stop according to the transport controls on the 1680. How do I stop the control of the 1680 to where it is only sending sync and how do I configure the td10 to trigger the dr660? I would appreciate any guiding steps.
