Crosti 9F TTS Sound and Standard 9F TTS Sound - Any difference?

[OzzyTrains]

Would anyone know whether there is any difference between the two TTS decoders. I purchased one of the centenary Evening Star locos and I want to add some sound to it but most of what is available is the Crosti version. I thought someone else might know if there is any difference between the two decoders and if it would sound the same as a normal 9F.

Thanks,

Harry
