Is the 2011 update legally obtained? if not you will experience corruption on new styles.

Otherwise have you run the checksum test here:

Audya Problems?

Yes i have

If i remove some parts of the midi file source it works but i dont see any reason for that

Hell filipelou thats an expensive way to get an answer, I would not be going down that route, your local Ketron man can't he help, has no one else had this problem or is it just you, have you emailed the factory or ring them, how old is your Audya.

Tony

No .Unfourtenly you and ketron owners know very weel how ketron support is .

For everyone that have this problem i have found it by myself.The problem is a midi controller that somepart has called expression.

Filipe,
can you explain bether...???

Let me do more tests first until i reach a conclusion.

After several hours of testing i have one conclusion.When you compile one midi to style and you want to add subsequently user audio drum,you have a limit of notes and controllers in that midi.If you exceed that limit when you save in audya with the user audio drum inserted you get the corrupt style error.
