Actually Cakewalk by BandLab (CbB) supports the ARA 1 standard but has not implemented support for ARA 2.

Questions in the old Cakewalk forum about if or when CbB will support ARA 2 were not answered by the CbB development team. The question has not been asked in the forum.

I believe Sonar Platinum included Melodyne Essentials which is limited to one track at a time. CbB includes the free trial version of Melodyne as an optional add-on. However, once the trial version is installed it is not listed in Windows Programs separately so it can later be uninstalled. CbB can access any third party content you may have accumulated as a Sonar user so if you have Melodyne Essentials or if you have the full version it can be used in CbB.
