If Softube doesn’t add the plug-in to your account, maybe your account details weren’t complete. My weren’t. When so completed them, all went as planned.
Also didn’t get a Roland D-50, for which I’m happy now, but I would have loved their JD-800. Got a measly Korg DS8 instead. And the first Alesis QuadraSynth, much later followed by a Fusion. Diving ITB is less expensive. But I did get that Sequential Take 5 last year. Couldn’t help myself.
