Thanks Jonathan. Unfortunately, my C expertise is kinda poor and I'm still lost. I see it's got something to do with [exp] but haven't got my head around the function needed to emulate it. I'm making extensive documentation about Pd, so I'd like to write about it. I find it worth noting.

In the patch I'm sending, which was my attempt to get this right before reaching the list, I was able to emulate a bit reasonably with [expr pow($f1, 0.25)].

Cheers

From g_vslider.c:

    if(x->x_lin0_log1)
        out = x->x_min*exp(x->x_k*(double)(x->x_val)*0.01);

Where x->x_k is:
        log(x->x_max/x->x_min)/(double)(x->x_gui.x_h - 1);

And x->x_gui.x_h is the height of the slider

hi folks, out of curiosity, what's the exact log function used in the slider? I'd like to emulate it.

cheers
