Hi Michael,

could you explain, what did you mean by "firm0000.snd contains new (changed) internal sounds."???
I do not own the X1, but I have read everywhere, that the X1 contains 24 MB PCM ROM with internal sounds. ROM ist read-only-memory it cannot be updated. Did you mean the ADSR etc. modifications of the internal sounds stored in RAM location?

Regards

Marek
