I use a Digitech Sdrum with my kemper stage. I use the upper loop as « aux in » to connect the Sdrum which is working fine.
It’s very difficult to synchronize the built in looper with the drum. So I would like to use an external looper. I made some testing with my TC Electronic Flashback X4 before buying a Jamman that can be sync with the Sdrum.
Without the Sdrum, I set the SEND1 as “Master Mono” and the flashback return to upper loop as “aux in”. Even with kill dry on, I have a phasing issue when looper is connecting.
Does someone know how to use an external looper without phasing issue?
