Thanks for all the replies! You are totally right. Pre/Post doesn’t work if Looper is NOT engaged through Preset Mode (and not setup in advance by H9 app).

Which is a pity. I usually just jump to Looper with the Encoder knob. I understand that the problem lies with the mechanics of how Pre/Post switching works – you have to press and hold the Left Footswitch and in Looper’s case it’s reserved for Record function.

By the way, all the regular delays still can be routed Pre or Post without Presets. I wish Eventide would consider “Presetless” Pre/Post routing for Looper for the next update.
