It pans at the opposite on first repeat and alternate with feedback.
If your signal is mono, it stays mono.
If your signal is panned left, first repeat is in the right, and alternate pan for repeats.
If you want to do a ping-pong delay, pan your signal with an lfo. If you want to keep neutral panning for dry signal, you need a 2nd track.
Neighbor track doesn’t seem to have effective balance setting. Lfo wouldn’t work. But the delay track can be a Flex recording the dry source*. Big advantage : to can also modulate pitch an other Playback page parameters.
*Play the T1-T8 recording with the Flex, and place a trig with +1/384 microtiming.
