Whatever it is, I hope this means that they are starting to update the unit at a faster pace, since the last update was less than a month ago.
In all fairness, their launch was around Covid-19, so I can sympathise if schedules got messed up. I know that a lot of users were pissed about that, and I kind of jumped in just when things got moving, so my experience is hardly representative of those who have had to suffer with a unit that wasn't completely finished out of the door.
Still, Fractal Audio and Kemper have been doing major improvements to the unit in recent months (and years), so Neural really needs to emulate that kind of customer-centricity.
In particular, while I think this might just be another PCOM release, I'll also be looking to see whether more features are added to the unit, as that is equally important at this juncture, imho.
I have bought five plugins from them, on top of the unit. Kind of feel a bit silly, actually. Despite that, PCOM compatibility can wait, it would be far better if they improve the algorithms for the delay and the reverb for a start.
