Pd tries to optimize the DSP graph by reusing signal buffers. The
actual results naturally depends on the structure of the DSP graph
at hand. Don't worry about the details, the only thing you have to
keep in mind is that buffer aliasing can always happen, no matter
how many inlets/outlets you have and how they are created.<br>

Buffer aliasing is the very reason that you should read all inlets
before writing to any outlet.<br>

<p>In Pd, signal inlets and outlets can share the same buffer.
Therefore it is important that for any given sample index you
never write to any outlet before reading from all inlets.</p>
<p>In your case, you have to first make a copy of all input
signals before passing them through to the outlets. You can
allocate the necessary intermediate buffers in the dsp() method.</p>
<p> </p>
<blockquote type="cite">I've been working with variable amounts of
inlets and outlets</blockquote>
What do you mean by "variable" inlets/outlets? Do you mean that
the number of inlets/outlets is determined by creation arguments?
In that case, this is not related to the problem at ahdn. Buffer
aliasing can happen either way. (It actually depends on how the
surrounding objects are connected.)

<div dir="ltr">Hey all,
<div><br>
</div>
<div>I've been working with variable amounts of inlets
and outlets and for the most part it's been working
fine. If it's only variable inlets and the outlets
are fixed, or vice versa, it works fine. However
when both are variable I can't seem to get the
inlets to go to the correct outlet. My current code
is cycling through the inlets and outlets in pairs,
but for some reason this isn't working. Any
thoughts?</div>

<div>Thanks</div>
