You best bet is to try converted ketron styles for latin. They will have the best latin styles of any keyboard for bachata, merengue, cumbia, reggaeton, salsa, etc. Korg latin styles are less to be desired also.

I had the same problem that you have. I owned a Yamaha and had to sell it because the latin styles were not to par. I ended up buying an Ketron Sd5. If you mostly do latin, you will be better served with an SD5, or Audya.

Good luck
