Done or ot done where is the difference? I created patches I don't use for live, only to make experiment
Iphone apps have a fee, many software have costs.
Not only the time is a cost, the experience also!
If you can do the same patch of course you don't need to buy.
The important thing is the possibility to choice!
I bought several IR for my patches, some of them are unuseful but this is part o my research.
I am really happy because I bought IR who play very well.
No offense of course! These are only personal opinion :)
