Sorry, but Track Groups do not define an order so what you are describing is not possible. Equally what you are describing would be affected by the order in which you schedule - i.e. it is possible to schedule far in the future before you schedule in the near future so would not produce the outcome you desire.
I created a clock in order to schedule it the same time every day. The clock selects files from a track group (e.g. "Track Group A") and then from another track group (e.g. "Track Group B")
I want the clock to select the next track of "Track Group A" each day (in sequence) and not to select randomly a track from that track group. I do not care if the clock selects randomly tracks from "Track Group B".
Is this feasible?
Thanks in advance!
