dynamic poly~ and M4L issues

Peter McCulloch — Mon, 15 Aug 2011 17:19:33 +0000

I’m having a lot of problems when using poly~ in M4L as an object wrapper. I’m using it to switch between different oscillators, and it’s really not working once I get it into Live. It makes sound, but the pitch of the oscillators seems to be stuck on something really low since I’m just getting impulses.

I’m using a change object to prevent the constant updating of the chosen patcher, but it’s not helping. The code within the poly~ is very simple, and it works fine in Max, just not Live. I had something similar happening with another patch and I replaced it with mute~ and subpatchers, but it’d be great if poly~ worked in this situation. Does anyone have a similar issue?

Here’s the selection code:

P.S. No upsampling, vs or anything special for the poly~, and only one voice.

all i can say is:
i feel a bit guilty because i keep meaning to report this exact bug and never get round to it.
yes, i have exact same problem – M4L is not allowing the dynamic switching of poly~ patches, period.
however, for spanner in works, i DID have this working fine as far back as max 5.1.3-ish. i think this bug might have been added in 5.1.7 or 5.1.8.
similarly, works fine in max standalone, but not in M4L. could not get it working in editor either as far as i could recall.
you can actually check his by simply turning the dynmaic-poly~ section of the standard help patch into an M4L device – does not work.
sorry i do not help.
would be good to get this fixed for this version of M4L and not have to wait for compatibility to Max6.

Hey, it’s good to know I’m not the only one.

I confirm this behavior.

ok. strange. i managed to get the poly~ dynamically reloading. it needed the FULL file path AND “.maxpat” at the end. weird. it seems to work though on initial tests. (before, i just used the file name as it was in the same folder as the .amxd). have not tested ‘frozen’ yet though. can it really be this simple? or am i being an idiot (likely)? [pointless code demo at end of post].

however, for me, big problem still. my poly~ patches contain an embedded pfft~ patch. inside the pfft~ patch is an [index~] with a m4l device-wide “—” unique identifier in the name. the actual buffer~ is in the parent .amxd. whatever i do, on reloading the poly~ dynamically, the device can never find the unique identifier OR the buffer~. it loads the index~ in the pfft~ as if it is not even in m4l – i.e., with the actual three slashes “—” characters rather than the replaced unique identifier number. so, with dynamic poly~, it appears embedded “—” identifiers for buffers/etc do not pick up the load order correctly. makes sense? no, thought not.

anyway, have either of you two officially bug reported any of these issues to cycling? i am sort of scared to ‘cos they are busy on max6… i assume they have not seen this thread.

hey pid, I confirm your findings (poly patch with full path and maxpat ending) also. this one works for me too. But I havent tried your workaround patch yet.

No, i havent reported this. Since I stumbled upon this thread by accident. Its not a actual problem for my patches, but its always good to know about.

Dumb question, but do you just send mail to the support folks for bugs and the like?

i guess so. i am dumb too of course.

i’ve just realised how desperately i need this feature back!

who will take plunge?
