I play a Tyros5 and have noticed that most styles, even commercial song styles - have patterns that are 2 or 4 bars long. This becomes stale very quickly. I came across these videos (URLs are below) about the styles on Lowrey organs that "evolve" in time and change appropriately to the music, since the patterns used are very long. See the discussion in the videos about the styles. Why can't we have such styles in our Yamaha keyboards either from Yamaha or commercially? Is there anyone selling such long-pattern styles?
