Hello DeaconBlues09,
Have you tried this? Even with the entry "1 note per beat" and a phrase lenghth of 1 the soloist creates phrases of two notes, an eighth and a quarter note. I tried this with a lot of different style settings and did not get any "one note per beat" solos (screenshot is from my localised Band in a Box, so options are labeled in German language). Could it be that it depends on the .ST2 chosen as the "style knowledge base"?

May be this is a question for PGMusics new FAQ or tutorial video forums.
