excellent Cees.

there is an easy way to avoid surprises in the new keyboard.
always copy the style and pads you use in a song to the composer and user pads. Then when you save the song with composer, pads, sound etc it will play with the same patterns in the next machine.

every new model I generally end up copying composers into peoples songs and resaving their panel memories for them from preset to composer in order that their songs sound the same
