I know exactly what you mean about NI. I had an older product but to use it on a new IntelMac I HAVE to upgrade. They've also dropped a few older products of late. I have heard the brains behind NI is an old accountant so that explains alot...
In fairness to Arturia I do like the fact that their upgrades from say PPC OSX to IntelMac OSX were free upgrades, and that when they improved things on the MiniMg V this was also free. It shows a good deal of respect to its customer base...
But on the other hand they have of late fallen with the numerous bugs esp on the Prophet V :evil:
I just wished they'd sorted these out before diving into the Origin project. However I do have faith that Arturia will sort these bugs out very soon...
To get over the NI problem/licence/upgrade issues, i've trimmed back on my softsynths so i'm not at the mercy of constant paid upgrading etc and I use Logic's synths + 2 Arturia synths..
I suppose the only answer would be to use hardware.... no licence, bug fixes or chasing paid upgrades ever !!!!
