In the German forum they mentioned that they had invested 1.3 million euros in developing the soundset (throughout the past 10 years).
Thats no proof of anything... That depends on how you do your calculations..
If you create the sounds yourself and charge �800 for evevry hour you spend, then thats not a lot of effort..
If you only calculate the expenses outside of salary from the owners, then its a huge sum for such a package...
