I'd love to suggest Sibelius also accepts plugins with the plugin format *aax.
The sad story behind this is that Gibson has killed off Cakewalk, the product will neither be sold nor developped anymore. (Please see http://www.cakewalk.com/Gibson-Announcement.)
As a user of Sibelius (8.7.2) it was a small step for me to replaye my #1 DAW Cakewalk Sonar by ProTools (12.8.2), but alas, ProTools takes only plugins with the format .aax.
By this it would be easily possible to link projects started in Sibelius with sessions in ProTools.
