Has any one had any experience with multiple mice that they would care to
share on the list?

As a situation I can imagine using multiple mice would be quite useful in a
range of game-like multi-user systems.

Do you need multiple pointers ? If not, using the [hi] object could 

do the trick. I never used multiple mice of the same model etc., 

though. So I don't know/remember if they appear in the [hi] object 

You can have a look at the list archive as well. Given such questions 

have been discussed, you may find useful infos, there.

i've started using this some time ago, but got stuck, and forgot about that 

until now. i tried to make external to read all data from all mices in 

system, but i've run into two serious problems: how to disable other mices 

from affecting system pointer, and how to make independent thread that will 

read this data all the time(when it arrives actually), and to output it to 

it is quite defunct now, as it stops main max thread if you don't move a 

mouse, but if anyone wants extern/source i'll dare to look for it in the 

ps. sorry for typos, just reinstalled system and it somehow misses spell 

it could actually.

Yes, thanks for that, it worked fine. I also forgot to reboot MAX after

Now all I have to do is figure out how to get basic displacement (i.e. x or

y data) data out of the mice rather than delta.

Should I find some way to calculate displacement from the delta, or is that

Yes, thanks for that, it worked fine. I also forgot to reboot MAX after
plugging in the extra mice� doh!

Now all I have to do is figure out how to get basic displacement (i.e. x or
y data) data out of the mice rather than delta.

Is that what mice generally do? (delta)
Should I find some way to calculate displacement from the delta, or is that
putting the horse behind the cart?

If you ever worked with a mouse you know it ;-)

It depends on your mouse, try to track any value the mouse is putting 

out through Hi. If its only putting out delta values, what I guess it 

does (how should it find a reference point? think about it!), unless its 

a trackpad or a tablet, you need to calculate absolute values, like the

It depends on your mouse, try to track any value the mouse is putting

a trackpad or a tablet, you need to calculate absolute values, like the 
mouse pointer on the screen does.
Look at the mousestate object (which you could also use by the way) and 
see how it does its job.
