bpatcher – file and arguments greyed out means…?

Nov 12 2012 | 1:51 pm

(latest Max 6 and OSX)
I have one specific patch that when I load it into a bpatcher, the Patcher File and Argument(s) options grey out. What does this mean?! (And how do I fix it?)

I’ve tried copying the contents of the patcher into a new blanks patcher (in case it’s something to do with the settings in the patcher inspector), but I get the same result with the new renamed patch.

"embed patcher in parent" checked on in the bpatcher inspector ?

No, I checked that straight off.

Old news now, I know, but I am constantly plagued by variations on this problem — especially when duplicating bpatchers — but I can never get anything failing consistently enough to post here. It comes and goes in mysterious ways. I deal with it by putting my arguments in before I choose the patch to load, so if the args field locks, it won’t matter. Ugly, I know…

agreed – i see this spuriously aswell. i tend to find closing everything down a restarting often cures it, but have no consistent way of reproducing.

really annoying, yes.
my workaround is to do a [script sendbox bpatchername args arguments] to a [thispatcher] object located in the bpatchers parent. haven’t found a better solution as the bug is completely random.

This bug has been around for some time — C74 is aware of it, so it’s on some to-do list somewhere….

This issue is still not resolved in Max 6.19 and is really annoying. It makes very difficult to do sets of voices using a model.
Another solution is to copy the bpatchers with the initial args into a text editor, change manually the args and copy back the text into the patch.

"box" : {
"maxclass" : "bpatcher",
"name" : "Voice.maxpat",
"args" : [ 12 ],
"numinlets" : 0,
"patching_rect" : [ 34.0, 198.0, 94.0, 236.0 ],
"id" : "obj-4",
"numoutlets" : 0
