the only bad thing is the fact that you can get a 90% similar sounding patch but the parameters are not exactly the same as the final patch and you get somewhat unfair ratings. as stated in the title, this is probably better towards people who want to get sharp at sound design especifically. as for producers in general, you only need to have the idea of what does which, but obviously being sharp at sound design is always an 'extra hand'. IMO it has alot of patches per lesson aswell, and since you repeteadly need to hear in-between your patch and the final patch, you can get tired of your session quickly.

Overall good and usefull, great for that daily one hour training.
