It is an easy to use tool but.....
It is an easy to use tool but the random function is a little bit pure, because it often uses the same effects twice, or random-results are not useable.
All effects can be made with your DAW as well, so finally Sound-Doctor is just an easy to use tool with unique design, layout and animation.
I paid 97$ for it - sorry, but this is to much for what this tool can do.
