Sure you do. Happens all the time. You don't even have to look outside NAMM '19 to see it.
Wampler Pedals demo'd their new Terraform. Which they said would be out in Summer. Much like Kemper, they've communicated that it's taking longer than expected and to hang tight. Nothing is 'fundamentally flawed'. But getting it right is taking more time than expected.
It happens. All the time.
Quit being so reasonable dude
I've had a change of heart recently regarding an editor. I used to have my Powerhead sat on top of a cab or shelf in easy reach. I loved how I learned how to twiddle the knobs and change menus quickly at home which was brilliant for use live; unlike if I'd spent all the time using an editor and would be lost without it if one of my patches I'd been working on didn't translate well a volume.
Recently though, i ended up moving my Kemper into a rack and it now lives at about calf height. Super handy for fast set up live and at home but a right old pig to tweak with an aging back. So now, I do want an editor and have bought a Windows 10 device in preparation. That said, I'm not complaining about the 'delayed' release of the editor.
Whilst I understand the frustration, I don't understand the lack of manners from those that feel the need to be rude or constantly negative about the current situation. I can't be bothered to argue with them though and it turns out that the block feature has a wonderful effect on my mental state when visiting this place, waiting to see if 3.0 has landed!
