I am on a Mac Powerbook 2.16 Ghz Intel Core Duo.

I instantiated matrix~ with 250 inlets and 250 outlets

and it all worked great. When I increased the number

of inlets to 500, Max nicely reported in the Max

window "resizing to 250 signals" and it all worked

great again. However when I increased the number of

outlets to 500, upon turning the DSP on Max crashed

immediately. So it seems that the matrix~ object has a

set limit for the number of inlets that can be

created, but no limit for the number of outlets.

So this leads to my following dev question:

In z_dsp.h I see that there's an enum constant

SYS_MAXSIGS = 250, which is the "number of signal

1 - when writing an MSP object with a variable number

of inlets I always have to check against the user

error of instantiating the object with more than 250

2 - There's no set limit for the number of outlets,

but there should be because Max/MSP doesn't like too

many inlets as well as too many outlets? If this is

the case what's the limit for the number of audio

outlets I should check for in my MSP objects?

Not sure without some investigation, but if it makes you feel better, 

Sorry if this sounds rude, Luigi, but we're focusing on what we feel 

to be more important issues at the moment (i.e. Max 5), and these 

questions are in our opinion really small issues that you've already 

posted without response (signal inlet/outlet count used to be 

restricted to 32, FWIW). I hope that this small bit of uncertainty

Not sure without some investigation, but if it makes you feel better,  
you can assume to be the same as inlets.

Got it. Thanks for taking the time to answer my
questions anyway.
