Beware of NOT wiring enough. <br><br>Of course, we've all seen what beautifully unintelligible spiderweb artwork people are capable of spewing out when they don't patch with the courtesy of showing their ideas methodically. But an invisible web of sends and recieves can be just as misleading.
<br><br>I like to use a combination, where there is a single [inlet] to a [route] that uses local [send]/[recieve] pairs within the abstraction. I really like this idea of Frank's to use one "master" send/recieve pair and then weed it all out with [route] objects: it makes it easier to remember what to type!

Pardon me for replying in this clumsy way, but I'm not sure how to<br>maintain thread integrity on my replies, since I receive PD-list in<br>digest mode. Since Kyle was kind enough to write me directly, I'm<br>hoping replying to him and his cc of the list will preserve the thread.

<br>that you wouldn't have with my second approach, i.e., you still have to<br>patch the output of [route] or [OSCroute] to the various places the data<br>is needed. Plus, you need to pack the sent information in one place on
<br>the parent patch -- another jumble of wires or an additional set of<br>send-receives. I think symbolic routing is a good idea in general,<br>though, so maybe these are not such important considerations.<br><br><br>carmen writes:

<br><br>One idea, which I've used successfully on another patch, is to add a<br>parameter to the abstraction which is a message prefix.<br><br>So, if I called [a_grain~ env samp xyz] the third argument 'xyz' would<br>be the message prefix (it could be anything one liked, even '$0' if you

<br>Each instantiation of that abstraction will therefore only receive<br>messages intended for it, and one can address as many copies as one likes.<br><br>What I like about this is the lack of wires. In the parent patch,
<br>there's no wiring (!). I just assign appropriate sends, with the<br>correct prefix, to my sliders, number boxes, etc. In the<br>abstraction(s), there's an appropriately named (with the $3 prefix)<br>receive object sitting right next to whatever needs the message.
<br><br>I do want to go to the next stage and learn how to persist presets, so<br>Frank's tutorial is particularly appreciated. I'll probably adopt his<br>system for its obvious advantages. I'm just trying to train myself to
