<p>I'm not an expert, but here some loose pointers (no pun intended)
on this topic which might or might not fit into your concept:</p>
<p>- I use only pd's internal messaging, not the iem libraries for
it, which probably allow for more interesting things.</p>
<p>- have a look at [jmmmp/dacm~] (dynamic) and [jmmmp/dacc~] (not
dynamic) for very simple concepts on connecting to audio output.
The problem with internal messages is that you have to know
exactly what is the number/ID of the object if you want to make
connections between objects. I'm not sure now if the ID always
increases in each session, even if objects created before are
deleted, or if the ID adjusts to how many objects are active -
probably the latter.<br>
</p>
<p>- I have deleted objects with dynamic messages by simulating
mouse actions (click and drag, then delete). Not very
user-friendly.<br>
</p>
<p>- when creating objects, I usually put them into a subpatch
dedicated for that, which can be reset with [clear(. But won't be
possible in your case, if you want to delete some objects and keep
others.</p>
<p>- instead of using dynamic connections, consider using $x
arguments in your abstractions for send/receive variables instead.
Probably easier to manage.</p>
<p>- an option could be for the patch to have all objects inside it
(no more dynamic patching needed), and make the connections by
dynamic routing instead.<br>

<div dir="ltr">hi folks, since Alexander was just covering dynamic
patching in PD on the <a href="http://puredata.info"
moz-do-not-send="true">puredata.info</a> site i thought i
might inquire about options for dynamic patching. i've perused a
few libraries like iemguts, and a new one called clj-puredata
using Clojure. i sent this to the dev about my use case and i
thought i'd post it here for some advice:<br>
<br>
<div>i want the player/user to be able to dynamically add or
remove instruments from a patch that is already loaded, in a
live performance situation.</div>
<div><br>
</div>
<div>i'm planning to have a master module patch with 8 slots for
8 instruments with approximately 10 control inlets and 2
signal outlets. i have currently 3 unique instruments to load,
and planning on more. all of the instruments have exactly the
same amount of inlets/outlets. all i need to do is load them
up, hook the I/O up to the slot, and delete them when desired.
the instruments will be abstractions, not subpatches. </div>
<div><br>
</div>
<div>i would just need a way for the slot to know when an
abstraction is loaded or deleted. i can uniquely name each
slot if that would work better for this, though i could
probably have a flag, number or string indicating what state
the slot is in - like 'add', 'remove', 'active' and 'disabled'
or whatever. </div>
<div><br>
</div>
<div>i have briefly watched a bit of the Youtube video on
dynamic patching, but rather than roll my own i thought i'd
inquire about libraries or externals that could handle it. i
think iemguts can handle the querying it seems, but the docs
don't make it clear how objects (abstractions) are instanced
and deleted or connected. i don't need to move anything - just
load and connect an abstraction directly under a slot or
delete it. any help appreciated!</div>
