when I use "brownian 1 2 0.5" it supose to give me

1's and 2's, right? but I'm getting only ones..

this object works well with intergers? or I'm doing something wrong?

You probably need to use explicit floats for all parameters, viz:

Otherwise you're in the integer domain and the output range is 1

But I don't know for sure. For Brownian motion I use lp.pfff from 

Litter Power. It's even a Starter Pack object. For more flexibility, 

Caveat: the syntax is a little different from Gerhard's.

Otherwise you're in the integer domain and the output range is 1
2, which would explain your problem.

Litter Power. It's even a Starter Pack object. For more flexibility, 
there's lp.pvvv from Litter Pro.

"brownian 1 2 0.50" gives you *many, many* 1s and *very few* 2s. The 

higher you set the variation parameter the more 2s you will get.

Well, the Brownian model doesn't really work with two integers anyway. 

The brownian abstraction is trying to simulate calculations in the real 

(float) domain by dividing the actual min/max into 65000 subdivisions. 

That won't fool a mathematician, but is probably good enough for a lot 

of uses in Max. If you're working with floats.

I'm not sure what sort of an effect you're actually after.

If you're looking for some kind of coin-flipper, perhaps with different 

probabilities for "heads" and "tails", you can build something 

following the examples from the early Max random objects tutorials. Or 

just take lp.bernie (Litter Starter Pack, URI below).

If you want something else... well, you can probably also do it with

I am also not quite sure what you are after. The interesting thing 

about "brownian" is the fact that you can adjust the distance between 

choices. If you just want a stream of random numbers there are 

several max objects that serve this purpose: random, urn, drunk.

RTC-lib and Litter give you many more options for generating events

i need to redo [drunk] in floating point. how are random numbers or brownian distribution are calculated?

i thought it was on the forum a few months back but i dont find it.

- then you create a random normalized float (lets just pretend there would be a max object called [noise] for this)

- then you scale the random float down to the max motion distance the user entered

and what about sign? random bool i guess?

 - you start at 0.5
 - then you create a random normalized float  (lets just pretend there would be a max object called [noise] for this)
 - then you scale the random float down to the max motion distance the user entered
 - then you accumulate that to t-1
 - da capo

and what about sign? random bool i guess?
