My family in Indonesia have recently purchased a Technics KN2600 keyboard, along with a PA system for sound.

They will be principally playing at weddings.

Here are some samples of the music: http://www.youtube.com/watch?v=RUUonI-z9pk http://www.youtube.com/watch?v=36vHZZjOlhE

and a typical outdoor event:

They also say they want to play some Western rock/pop.

Anyway, I have been asked to provide whatever enhancements I can, via SD card. This is given that they have no computer/internet access/understanding, so I will be loading the SD card and sending it by airmail.

Can anyone give me some recommendations for styles for enhancing things? Will anything labelled 'Technics styles' work? How is the keyboard at handling these and MIDI files?

Does anyone know if there are size limitations on the capacity of the SD card?
