I could use more styles but at the expense of the ones I'll never use. The PSR-740 has 160 styles and three user styles. It would have been better to have 3 styles and 160 user styles so you could load the ones you want, which in my case is swing, jazz and ballroom. I will say this though. If you speed up or slow down some of the other styles quite drastically you can find a lot of hidden treasures.
