Not every USB C port provides power in addition to data, so that remains to be seen.

Understood.
I think I can more generally phrase this is as:
“People who had gotten their hands on one, if they plan to use it with an iPad, how do you sort out the needs for USB-C connections for both Power, MIDI and Audio, assuming one would not use the internal iPad speakers”.
If anyone gets experience with this in the future, then I would love to hear back.
You just use a powered USB hub with the iPad and plug everything into that. Make sure you get a hub that will power the iPad (USB PD most likely) and not just the peripherals (some USB-A hubs).

I would just use a separate battery pack since it has a separate usb-c power input. This is a very smart design and something I wished for on the Polyend Play.

Hey mate,
Yes we have noticed this issue with displays on some units. We’ll have a firmware update next week that will address this issue.

this is great - happy to share this on Melbourne Instruments pages and credit you, of course!

An ableton session mode would be cool too, where you can dial through the clips per track and then launch them using the buttons. Ther reason why i didn’t like doing this with pads, is because you don’t have the names, only the colors. Which makes it difficult to navigate (for me).
Edit: I see that the new novation launchkey mk4 has very similar features, including this one. so i guess this must be doable 
hey David how far is the manual? I get that showing it at NAMM and shipping straight away is fantastic, but without manual isn’t. cheers!

Just got one.
Would say yay, but it won’t connect to Ableton.
Installed the app, and it sees the device and its mode.
Put it in mix mode.
Started Ableton - doesn’t do anything.
Tried the transport - does nothing.
It does look like Ableton’s receiving MIDI from it (from the TRH MIDI monitor)
Checked setting snd set it to track/remote.
Tried external sync.
Am I being dumb or what? @Honeysmack
Does it need a control script?
Where’d you get it from, if you don’t mind? Europe or States?

managed to get transport controls to work, but midi learn in plug-in mode isn’t working for me.
Im having the same issue via USB. Mac recognises it, Ableton recognises it, the Roto setup app sees it, but the screens arent showing any ableton mappings 
it seems to be sending midi too. Did you find a solution at all? Got it from Signal Sounds too. Might be the latest FW update or something?
Call Luke from Signal Sounds a legend:-
"So I had a similar issue when testing the unit. In order for the Mix Mode and Transport to work, Roto control needs to be a control surface in the midi settings menu.
If it is not showing up in that drop down; a restart of ableton and the unit should make it show up there. Also good practice to make sure Roto-Setup is downloaded! I noticed that once it appeared in that menu it never disappeared, it was just the first time getting it to show up that may need a restart.
I can’t see the manual on their site though they may be able to sort that out with you via email; either way I have fed back this info. Here is a quick start guide (it doesn’t mention the control surface part which I also mentioned it should!)"

it’s working for me now, discovered I need to expand the plugin in control mode to get third party plugins mapped.

Ahhh I love Luke. Legend is a very fitting description. Will try this out soon as my update finishes. Thanks!
edit: Yup. That’s sorted it. And this is the coolest thing I’ve ever seen!!! I’ve never seen/understood the point of Roto faders/pots but I completely do now.
Hoping to get these mapped to some stuff on my Disting NT (eventually) as I’ve got a whole convoluted mixer situation going on there and the immediate visual feedback would be fantastic.

Please ensure you select ROTO-CONTROL as a ‘control surface’ and select it again as an INPUT and OUTPUT device in Ableton Live’s (MIDI) settings page.

Firstly, I love this device - love the buttons for muting/unmuting tracks, love the screens.
Until I saw your post I had the control surface selected (as per your screenshot), but below I only had “track” checked under “input ports” and nothing checked under “output ports” and it works broadly fine.
I say “broadly” because:
Mapping 3rd party plugins doesn’t work for me at the moment. I expand the 3rd party app Ableton device (the downwards triangle), press “configure” and bring in the controls from the plugin’s UI that I want to map. I learn them on the root control in plugin mode - all good. But when I add another midi track with a different 3rd party plugin, plugin mode still shows the parameters that I mapped from the previous 3rd party plugin. In other words it seems like it doesn’t diffferentiate between different 3rd party plugins - there’s just one set of parameters for any non-stock plugin. If I delete/re-learn the mapped parameters on the 2nd 3rd party plugin, it will also change them on the 1st 3rd party plugin (and they won’t work on it anymore). In other words it behaves like all 3rd party plugins are the same plugin. This isn’t expected behaviour right? Maybe it’s because I haven’t checked track/sync/remote on bother input and output ports in settings…. Will try that now.
Other than that, it works great. Stock plugin mapping works flawlessly.
Are you able to use 2 different 3rd party plugins (with different mappings for each)?
Update - checking track/sync/remote for both input and output unfortunately does not resolve my 3rd party mapping issue. If anyone else can confirm that they’ve been able to map 2 different 3rd party plugins (and have the roto control remember them) that would be appreciated
