Dr Z. started making his own because the public ones were not representative of his product. A lot of what is out there lives in this arena.
For me that is a poor example as the DrZ official pack is one of the least inspiring pack I have ever purchased. There are plenty of great profiles of DrZ amps but for me personally none of them are in the official pack.
The market is completely oversaturated.
No argument from me here ? unfortunately a lot of the rubbish os from commercial profilers who would be able to implement DRM signed profiles in the proposed closed ecosystem. I still can’t see any argument to add DRM to the KPA.
