Owning both S1 and cake how do they compare in Integration with Melodyne. I know Celemony and Presonus are tight partners does Cakewalk use Melodyne as effectively?
I don't know if Cakewalk is ARA2 ready yet but Studio One, Logic Pro X and Reaper are. Here is a demo of a video showing it in action with Studio One Pro.
Demo Video So what exactly can ARA2 do? Here is a quote from Celemony.
"With ARA 2, the exchange of information between DAWs and plug-ins is even more comprehensive, which makes additional applications possible. The new ARA 2 specification allows, among other things, the simultaneous editing of multiple tracks, the transfer of chord track information between the DAW and the plug-in, seamless clip borders that make the manual setting of crossfades superfluous, Undo interlocking with the DAW, and much else besides.
To profit from the new possibilities, both programs – the DAW and the plug-in – must support the ARA 2 specification. Fortunately, ARA 2 is considerably more flexible and can be integrated more easily into a multitude of DAWs as well as supported by a very wide variety of plug-ins. What features then become available depends, of course, upon the specific plug-in and DAW in each case involved. One pairing may allow only simple sound editing, another perhaps even automatic tempo and harmony adjustments."
