Thanks for your code. Your "iReceivedInstrument = cChanInfo.iInstrument;" will not work correctly since you have to reset it correctly. But I want to store the complete info instead of the items separately.
I will do the implementation of storing the complete info now, then you can change your code to use this.

Another thing: I do not want to have another sort function. Please use "CAudioMixerBoard::ChangeFaderOrder ( const bool bDoSort )" but add a new function parameter telling the function to what parameter it shall do the sorting.

Ok, I have now changed the function:
void CAudioMixerBoard::ChangeFaderOrder ( const bool bDoSort,
const EChSortType eChSortType )
But not tested the sorting by the instrument.
