Hello,
You can push the bottom left encoder to turn Tempo Sync on, then tap in your desired temp with the right footswitch.
Any of the delay algorithms can give you this synced ping pong effect. Set the Delay Mix at 12 oclock so you can hear both voices A and B equally. Adjust the delay time A/B knobs to get various time differences between the 2 delay lines.
Connect the stereo outputs of the pedal and you will hear the left/right delays in either channel.
Let me know if you need any other help. I’d suggest experimenting with the pedal, checking the user manual, or watching YouTube tutorials for more information: https://s3.amazonaws.com/com.eventide.downloads/Product+Manuals/TimeFactorManual.pdf
