I haven't loaded up a song that has some instances of blackhole (again, not what you think) for a couple of weeks and, even though I have an authenticated iLok license, I get a message while Cubase is loading that I only have x days of this Blackhole demo left.
I assume this is another bug in the software. Eventide have me over a barrel – they make beautiful sounding plugins that are plagued by bugs. Do i keep using them or do I ditch them? My answer is I keep using them. From what I gather, there is a relatively small team working on the software so I'm happy to cut them a bit of slack while they sort things out.
I am confident they will get on top of the issues with the native plugs – they just need a bit of time. The quality of the sound is worth the wait.
