A misunderstanding because you are apparently not aware of
how Aeolus is controlled. With the default instrument setup
there are around 55 'stops' wich can be switched ON or OFF
individually. In general Aeolus could have up to 256 of such
binary switches. Not all combinations make sense, but there
are still zillions of them that do. Such a system does not
map to anything standard in MIDI, but it is how a real pipe
organ is controlled.

Aeolus can store combinations of these switches as presets,
and you can then load these presets using the standard MIDI
bank/preset messages. But the discussion is about the format
of MIDI messages to control each switch individually.



Io lo dico sempre: l'Italia è troppo stretta e lunga.
