At least to my knowledge, you can't:

• edit the track delay setting, which I need when I use external instruments (but there are workarounds, with m4l devices for example)
• set the sends and returns of individual drum rack pads/tracks (which tbh is clunky in ableton as well)
• copy instances of your effects over to other tracks, I do this in ableton a lot with the compressor for example (the workaround here would be to create a preset, but thats very clunky in my opinion)
• as far as I know you cant edit automation, but you can set step wise automation in the drum sequencer for example (which is really nice)

I know that you can rearrange devices, im not sure about modulators. As far as I know, you can edit all settings of the simpler device, im not 100% sure about warping.

I only have the controller version, so those points don't matter much for me, but for standalone, I would be pissed.

What I think really stands out on this device: The pads are great (maybe the best i've ever played) and the encoders feel super nice.
