Most waves are already available on the Kronos, at least from the ROM and also from some CARDS. You can find them in ROM m(ono), under tab Wavestation:
Wavestation ROM 32-515 = Kronos Wavestation bank 488-971
Wavestation CARD2 32-79 = Kronos Wavestation bank 972-1019
Wavestation CARD3 32-97 = Kronos Wavestation bank 1020-1085
Most of the waves are exactly the same. However some are a bit different, at least compared to the ones in the KLC version of the Kronos. Sometimes the pitch is a bit different, but also the sound is not always the same. I am not sure how this is possible.
Take for example ROM11 113: Tambourine. The pitch is 20 semitones lower than the KLC version of the WAVESTATION!
Other CARDS: some have the same sounds as the CARDS mentioned above, but there are also some sounds I was not able to find. So I think there are some sounds missing from the other CARDS that have been available for the Wavestation.
