Hello, this is a question about MAX 4.63, which I’m still using exclusively, and an error message I’ve never seen before, followed by a crash I can’t explain.

As soon as I added a reset routine, wherein counting down to zero triggers a “break” to an uzi and a “clear” to two pipes, this message now appears in the Max window: 

"freeobject: 16ab29a0: bad object" (the hex number varies each time) 

and eventually it crashes (sometimes immediately). Here follows the start of 1 report on such a crash. I'll happily send the complete report and my patch to anyone interested.

Sure hope someone can tell me wassup. I’ve hardly ever told an uzi to break in mid-process before; is this fraught with peril? Or is it the pipes? I use one pipe to separate the dumped pitches, and a second pipe to measure the note releases. Bad idea?

Hello, this is a question about MAX 4.63, which I’m still using exclusively, and an error message I’ve never seen before, followed by a crash I can’t explain. 

As soon as I added a reset routine, wherein counting down to zero triggers a “break” to an uzi and a “clear” to two pipes,  this message now appears in the Max window: 
 "freeobject: 16ab29a0: bad object" (the hex number varies each time)  
and eventually it crashes (sometimes immediately). Here follows the start of 1 report on such a crash. I'll happily send the complete report and my patch to anyone interested.

I have not had problems with Uzi and break/pause. Without seeing your 

patch it's hard to say what might be going on. Judicious use of a 

defer or a deferlow between the Uzi and the pipes might help.

Aha... Slipping a defer object between the pipe and its target indeed made for a successful prophylactic... Thanks for the tip. Though now I still don’t know what “freeobject bad object” means. It’s not in the error chapter of Max Topics.

I used to use deferlow to be able to loop back in my programs without stack overflow... until Stefan Tiedje told me deferlow puts your routine “on the scheduling cue instead of on the stack.” I’ll finally admit my ignorance and ask now: Is that a bad thing? It sounds like it— am I bothering the part that does “housekeeping chores” to involve it directly in my higer-level program? I dabble in a little Max and sequencing and DSP-mayhem, and don’t know much about the deep-down machine processes underneath it all.

Way back when I started using Max, in the System 7 days, I discovered if I inserted “delay 0” or “pipe 0” at the end of a process before looping back to the start, this was enough of a hiccup to be able to loop without crashing. I think of it as telling Max “Stop and count to — oh, never mind.” It still works, and I’ve gone back to using that trick. But which is better, defer or del 0?

First off, you must be using typographic quotes. Your messages are 

coming through like above on the mailing list.

As far as [defer] vs [del 0] or [pipe 0], I think that defer is the 

way to go. All you are trying to accomplish by any of these methods is 

to push off some calculation to a different time.

Both your quoting me and my original look just fine on my machine here. I write my messages on a Mac and post them on a public Windoze machine at the library... that might be a complication.

It's definitely a mailing list vs. web forum thing. For example, with
