Yes ... that is a decision of design ... the callback is when you release the slider not when you move the slider ... and you are rigth i'm musicien .. i want to listen the changes in realtime, but in this way the edit changes (undo redo..) save all the "points" and is not usefoul. I was try do the callback in realtime and store the edit changes only when you release the mouse but for a extrange reason .. (probably the extrange reason is i'm a very bad programmer :-)) not save the correct values. I need to explore more things in fltk toolkit, i will work on it. > 2) The note-on's regularly produce a slight click, probably because the > waveform immediately goes from "silence" to "full level".

Yes ... you rigth ... i have a personal battle with this "rustic" ADSR, in fact what does the marimba slider is adjust the attack, also i want to emulate the "click" of Hammond (H..organ..d) organs, and do it with the ADSR is a way to save CPU resources, probably not the best way :-) ,another thing to work on it. Thanks for your comments. Josep
