Correct useage of MCHAIN object

Hello to all,

I have a small patch (attached) where i'd like to implement Markov chains (higher than first order chains) to help make decisions in a larger generative patch i'm making. I have come across Markov chains and understand the principle behind them. However, being fairly new to Max and still working through the tutorials I am having trouble understanding if i am using the MCHAIN object correctly.

In this patch, i have wired up the MCHAIN object and seem to have it working. A bang comes through to decide on a choice of note duration from a COLL . Can anyone tell me if i am using the MCHAIN correctly in this instance? I thought i would have to create a matrix of possible states and weights to feed into the MCHAIN.

here's the patch and many thanks in advance for any help! I guess only download if you have access to Richard Dudas' Mchain object.
