Hi all,

Thanks for all the replies. Here are my comments:

Even if its precision is that low I hear audible clicks when I feed 
numbers without smoothing them with line. If I simply connect a number 
box to it and I use my mouse to scroll up and down the numbers 
relatively fast, I hear very clearly some unwanted artifacts.

Same as above. The interpolation done by the object works well up to a 
certain limit, but if you are feeding a lot of values and if the changes 
are large enough, the clicks will be heard.

I think I understand what you propose. I will try to implement this and 
see how it goes.

Thank you all for the help, I really appreciate it.

Cheers,
