I am using the phase inlet of two cycle~ objects to control stereo-spread of a sound source, but it appears I am missing some maths.....it functions ok, but there is a slight increase in loudness when the slider value is near the centre, tapering off at either min or max value; the patch below illustrates the problem. I would like to achieve a stable and uniform loudness level across the parameter range, from mono to stereo.

Apparently ignorance IS bliss.....I swapped the phase-inlet control for a simple line ramp, to control the amplitude scaling of the channels and the loudness bump is gone

Would you mind posting a patch showing your solution? I'd love to see it - I don't quite follow your explanation, but it sounds useful. Thanks!

If you look here on page 74 it should help

thanks for the great source; very 'layman' friendly!

Sure, this patch illustrates how curved and straight line scaling of amplitude effects panning and also "stereo spread" to some extent, but in this example patch I just have a simple mono source going both left and right. But in my granulator it works like a dream......yummy stereo multigrain goodness!

Thanks Brendan, much appreciated. I understand the general concept of "pan law" and have used various implementations - I just didn't follow the specifics of the explanation in your original post.

Cool, glad it helped - yeah thats a good resource.

That site and an old emu manual is all anybody really needs.
