Some guys have found that the Dopamine Set which is based on PA600 factory configuration, has some differencies with PA900 especially for styles location. Consequently, the songbook of the PA900 is not 100% compatible with the set.
Kalou did a version of the set based on the PA900 factory configuration so that the original songbook of the PA900 is 100% compatible.
I was not able to test it as I don’t own a PA900 but everything seems very close to the original one.
Thank you to Kalou who built this set and contacted me to make it available to all of us.
Dopamine – Kalou 2.5 compatible with PA900 songbook
Note that I still recommend the original Dopamine 2.5 set for PA900 users who don’t need songbook compatibility, because some styles are missing in the newer set.
Dopamine for Korg arrangers 
Can somebody make a pa3x version please? Cos pa3x owners have the same problem with factory styles and performances locations
Thank you very much for your giant work!
