@Adamixoye if I'm not wrong it's Midi Designer for iPad, I used it before. There's a few versions though, not sure which one he's using. There's the free version with ads, the free version without ads but can only put 12 buttons/switches/etc. on it, and the paid version without ads and with unlimited placement.

Anyway, another important update! I think this wasn't made explicitly clear in the manuals and I haven't seen it turn up in the discussion so far, but you CAN set both presets using the hub manager! I guess you could say I found a loophole around it.
The reason for doing so is so that you can set two presets on your OFD or MWBD2, and then morph between them.
Okay, it's done this way: When you're in the hub manager, for the pedal you want to set two presets, include it TWICE in Scene Viewer (the bottom panel). Make sure both are set to engaged, and under additional controls, scroll down to Current Preset, and set one of them to 1 and the other to 2.
When you load the scene from your midi footswitch or whatever, it will load the engaged pedals in the Scene Viewer from left to right. So the first preset you set in the scene viewer will be loaded into either preset 1 or 2 in that pedal, and then a split second later, the second preset will be loaded into the other slot. Now that both are loaded, morphing from one to the other works with the footswitch!
Some other things I discovered while figuring this out:
1) It only works if both are set as "engaged". I think if it is set to "bypass", the hub doesn't bother to send all the other functions, it just sends a "bypass this pedal" message.
2) If you don't set two presets in your scene, instead, you just set one scene (e.g. Preset slot 1) and set it to morph, it won't morph to the preset that you saved in your pedal's slot 2 beforehand. Instead, it morphs to your last used preset in the pedal's slot 2.
For example, say you used a scene with a multiband foldback 08 in slot 1 and a single band octave 20 in slot 2. Then you load a scene that only sets a clean boost in slot 1 with expression set to blend. If you blend, it will morph from the clean boost to the single band octave (at least if my ears don't deceive me and my memory is absolutely clear).
With regard to the earlier point about bypass, using the same example, if the second preset has clean boost with expression pedal morph in slot 1, and some bypassed preset in slot 2, it will NOT morph to the bypassed preset in slot 2. Instead, it will morph to the single band octave.
3) If you load a scene where one pedal is bypassed, e.g. slot 1 is a clean boost and slot 2 is some bypassed multiband octave 13, stepping on the slot 2 footswitch won't turn on a multiband octave. Instead, it will load the preset in slot 2 saved into the pedal itself. Likewise, say the scene loads a preset into slot 1. If you turn it off and on again with the footswitch, it will not load the scene's preset, instead of will load the preset in slot 1 saved into the pedal directly.
4) Finally, a confusing thing - earlier I said the scene loads the engaged pedals in the Scene Viewer from left to right. But if there's a bypassed scene, it seems to be the other way round. For example, if you just have two of the same pedal in the scene viewer, the left one is set to bypass while the right one is set to engaged, the pedal will be bypassed when the scene is loaded. But if the left one is set to engaged while the right one is set to bypassed, the pedal will be engaged. No, I don't understand why this happens. But it doesn't matter, since it doesn't affect morphing anyway.
So TL;DR: If you want to load two presets to morph between, load two of the same pedal in Scene Viewer, set both to engaged, and put the preset for heel-down position on the right.
Do let me know if this method is successful for you guys!
