I've just begun using this iPad (also available for Android, I believe) app with Cubase and it is gob-smacking!

I've no idea how well it works with other DAWs, but with Cubase it is a dream.
It's a fully-featured control surface, meter bridge, channel editor et al, conversant with Cubase's functions to an almost insane level of detail... Great though this all is, it's not what has me salivating.
Best of all... customisable soft buttons (12 that can follow you around on other pages, and 24-per-page that are under a dedicated tab.
Under Cubase 11 the system fires up with 91 (yes, you read that correctly - 91!) pages of pre-configured soft buttons (OK, not every button on every page is populated, but still...), covering so many Cubase functions I gave up trying to take them all in. Instead I deleted the lot and made my own couple of pithy pages to keep me sane and happy; I'll clearly have room to expand as the need takes me.
Creating a button is easy - select a button on the desktop app; click' command' to go into the editor; add a new EUCON command - over to the right is a long selection list of all the commands within Cubase; name/colour/iconise your button and you're done. But that's only the start...
The buttons created can invoke *multiple* Cubase commands, including those that would normally constitute a Cubase Macro - meaning that once created I just copy my EUCON file into DropBox, import it anywhere I'm working, and all my Macros will be there with me.
No more having to try to keep Macros and custom key combos in step between sites any more - one file import and I'm done!
I'll probably be back to this thread with more tales of this little beauty. I think my days of creating custom Cubase iPad panels in other apps may be over...
Now read the last word in the title of this thread again!
