Btw-- here's what that patch looks like in Pd-l2ork (attached).<br>
<br>
The array rectangle is orange because it's selected. I also changed
the size of the garray by click-dragging with the mouse.<span class="HOEnZb"><font color="#888888"><br>

No, the code I ported is from
vslider_set and vslider_draw_update
(might be different in Vanilla).<br>
<br>
In vslider_bang, math is done to output
the proper value. Without looking at
the code I would have guessed
vslider_bang simply outputs a stored
value like [float] does. Then just do
math to set the slider position or
calculate a new stored value from mouse
input.<span><font color="#888888"><br>

<div>Hi Roman. This is
turning out trickier
than I thought. A
friend explained the
code to me and got to
the following
equation, with min/max
values as 0.01 and 1
respectively.</div>
<div><br>
</div>
<div>[expr 0.01 *
exp((log(1 / 0.01) /
0.01) * $f1 * 0.01)]<br>
</div>
<div><br>
</div>
<div>For what I've
checked, it seems to
behave like your
patch. But it doesn't
do the trick I'm
looking for yet. I
sent a patch earlier,
and I'm sending it
back again.</div>
<div><br>
</div>
<div>The goal is to
connect a linear
slider to an [expr]
(with this so called
"log" function) and
then to another linear
slider. The idea then
is that this second
slider behaves as one
that was set as being
"log".</div>
<div><br>
</div>
<div>In the patch
attached I was able to
emulate it poorly with
[pow 0.25], but that
was before reaching
the list. See that if
I use this expr
function from the code
or your patch it
presents quite a
different behavior.</div>
<div><br>
</div>
<div>maybe it is some
sort of inversion of
this equation, not
sure. Apparently this
code converts the
"log" function values
to linear and I'm
hoping to get the
exact opposite. Got
it?</div>
<div>
<br>
</div>
<div>Thanks for looking
into this</div>

I am not sure, if
this is what you
want. It converts
the incoming linear<br>
range between 0 and
1 to a logarithmic
range specified by
$1 and $2,<br>
respectively by the
second and third
inlet. They behave
like the lower<br>
and upper bound
specified in the
[vslider]/[hslider]
classes.<br>
