Here is a forward from an "internet" friend who does composition with SB5. I 
sent him my tutorial. Here is some more info that seems real good in 
exploring the serial aspects of SB5

>In real serial composition, the composer would look through the matrix and 
>decide which of the possible rows produce interesting musical lines or 
>chord patterns and use and re-use them in different transpositions.  This 
>decision making process is next to impossible for a computer, unlike 
>harmonic progression rules in a tonal setting as included in my SMM, so SB5 
>does the next best thing by producing random selections.  It is unfortunate 
>in some respects, because serial music is anything *but* random.  The 
>initial tone row is normally carefully constructed with a view to producing 
>sensible intervals or chord patterns more often than not, and there is 
>nothing to stop the same row being used many times.  The only rule here is 
>that the whole row must be played before the next row starts.  SB5 follows 
>that but there is obviously no required connection between the different 
>rows, so the sound world is an accident rather than a deliberate creation.

>The siteabove illustrates another difference between orthodox serial 
>inversion and that possible with SB5 palettes.  The palette offers a custom 
>scale order different from the natural chromatic progression explained on 
>the site.    It can be used as described on the site by entering the 
>chromatic scale starting on the first note of the row, but it can also be 
>used to create a secondary order, so it allows a real muddling up of the 
>pitches and rhythms with inversion switched on. Whether this is a good idea 
>I'm not sure.
