Hi,

I'm trying to do a filter tutorial for my class, and it is the 11th hour. I have discovered that the metro object behaves wierdly in this patch, chucking out all its bangs at once (like kalashnikov).

SO here's the patch...

took me a while to find the problematic object (as soon as i was there, i saw the "here is the bug" sign....still, i'd suggest this for the award of bug obfuscating reports (it would be nice if somebody could make this into proper english))

anyhow, like always ;-) i would say that the bug is in the patch rather than in pd.

your problem is, that everytime [metro] receives a [1( (or [bang() it will _immediately_ start to bang. now the first [bang( will trigger the comparision which returns [1( which is sent to the metro, re-turns it on (and therefore immediately triggers a bang) and on and on...

attached is an illustration of what i mean.
