Pickup machines and tempo change

Been using OT (Pickup machine) as a looper device for a while. One question when you change from one song to the other by changing BANK/PTN and the Tempo changed, the Pickup machines says ‘overdub aborted’. How can i solve this?? One solution i’ve found was to erase all the cash recorded on the pickup machines after changing the PTN. This works but i want more simple way, like just clearing all the pickup recording’s cash memory.

What’s the behavior soundwise?
What do you want to achieve musically?
