Erol,
Thanks for the second lot of extra information. That was exactly what I was after. Now I can replicate your process and reproduce your problem.
I also found that the F chord produces F natural on the last beat rather than the required F#/Gb.
I've discovered that if one removes the 8 beat pattern so that only the 4 beat pattern remains, it generates properly (because there is no other alternative). The problem seems to be linked to intervals other than major intervals (i.e. F to E and B to C are minor seconds).
For example, if you enter the chords C, Dm, Em, F, G, Am, Bm7b5, C (1 per bar) and then generate, it's possible to see that the pattern is no longer considered, even though the weighting is set to 9 and the chord type is set to 'any'.
The behaviour is definitely inconsistent.
I help test pre-release updates so I will pass this information on to PG Music and include a link to this thread.
For those who know Stylemaker and would like to have a look at the style Erol is referring to, the SGU and STY files can be downloaded using the following link.
