I finished the editor, it's a little messy but it works ! how do you record the output of the faders?? hehe! to answer the question about what is the benefit of having the editor in the enviroment, at least for me it is sometimes useful to see the values I send with those knobs , or not always having to go to the synth to make some automation or edit something, maybe it's because i got so used to using logics softsynths , who knows but to me it's useful , cheers!!!
(By the way I love reaktor , building simple synths and that kind of stuff!)
