I have the Konzerthaus Organ and am setting it up to be played by midi keyboard controllers. One is an Evolution 49 and the other an Axiom 49 (both now from M-Audio). The Evolution refers to Middle C as C4, the Axiom refers to it as C3. I am aware of the lack of standards for octave numbering. However Konzerthaus utilises note and octave numbers for control of matrices. Could somebody please advise as to what octave numbering middle C is, when notes are referred to by Vienna Instruments?
In other words when Konzerthaus Organ suggests horizontal changes starting at C1, is this note 24 or note 36?
Thank you.
