Audio Playlist on MKRZero?

Hi

Three output signals from an Arduino UNO should control three individual sound files on the SD card of an MKRZero.(see attached diagram)

Has anyone an idea how I could solve this with the MKRZero - and
how could I solve this for example on base of the script "Simple audio player" ? ”https://www.arduino.cc/en/Tutorial/SimpleAudioPlayerZero"

Thanks for your hints

ok, a solution with the Zero for this application is too complex for me.

Now I will install this finished MP3 player, which I can control from the Arduino-Uno: http://www.produktinfo.conrad.com/datenblaetter/400000-424999/409666-da-01-de-MP3_JUKEBOX_MODUL_VM202N.pdf
