Hello Chris,
You can certainly load protected ranks of samples in your CODM organ definition (unless the sample set producer has specifically disallowed their samples to be used with the CODM for licence reasons, which only OrganArt Media does, to my knowledge).
However, you can't view/copy/reference the voicing and other pipe response parameters that the original sample set producer might have used if their original organ definition is copy-protected. You would need to adjust your CODM ODF rank parameters and voicing to taste (or to give a similar effect to the original organ response, if you wished).
(We do, however have logged an enhancement request for CODM ODFs to be able to reference rank parameters from 'full- format' ODFs.)
