Dunno if you have all been following the
Drumcore 4 thread. Its a somewhat similar situation. Old 32 bit plugins with some decent content that a lot of people have had difficulty getting to work reliably in 64 bit.
It looks like, after an eon, there is going to be an update early next year, They already have a presale. Those of us who have the Kits and Midi version, Kitcore are being told to upgrade to Drumcore 3 for $99, this basically buys a bunch of audio drum loops most of us have no interest in, then fork out another $99 for the upgrade in the presale. I for one am not impressed by this deal. It will cost me $200 to use my existing content. The extra features, like audio loops I do not want and there is zero information on the new features.
I hope IK are a bit more sympathetic to the existing user base or I predict a riot.
