I’m getting pretty good at ARA’ing into Melodyne from Cubase. Now I’d like to load multiple (well, at least two) tracks into the same Melodyne window. I’ve seen some videos “showing” how, but the key step seems to elude me.
To date, my process has been to select the track I want to fix, add a Melodyne insert to the track (bringing up the Melodyne window), click Transfer and then hit Play to load up Melodyne. The only way I know to get the other track into Melodyne is to do the same thing, and of course I then end up with two separate Melodyne windows.
Can some one provide a step-by-step process for loading up more than one track into the same Melodyne window?
To be clear about what I’m trying to accomplish, I have exported (from Sibelius in this case) an audio file of the vocal part I’m working on, and would like to have it alongside the human vocal track, for purposes of cleaning up timing and making sure pitch is correct.
(It occurs to me that a Melodyne macro to do the same thing might be very useful, since many singers sing from a vocal score. But that’s another topic.)
Select all the clips you want to be in Melodyne, right-click on them , and pick Extensions/Melodyne from the pop-up menu. This will bring all the clips you just selected into a Melodyne Editor window in the lower pane of Cubase. For my purposes, they’re pretty useless in the lower pain, so pop the window out into the full-screen view. You should now see all the tracks (potentially across multiple tracks) named in the top left corner of the Melodyne window, and all their data will be in the main Melodyne editing window.
From this point, you can just start editing all tracks in parallel if you like, but I usually find it more convenient to toggle which ones are active (orange) and which ones are just visible for reference (gray) to be able to control what I’m working on versus what I’m just comparing to have the big picture. That said, there are times I also work on multiple tracks at the same time.
As discussed in your previous Melodyne thread, the Transfer thing has no part in using Melodyne via ARA. If you’re using that, you’re probably using it as a VST plugin, and you won’t be able to work on multiple tracks in parallel.
all that @rickpaul said. Getting multiple tracks into Melodyne is easy IF you have the correct version 
If you don’t have the “studio” edition it won’t work with multiple tracks in 1 window. I don’t see you mention which Melodyne version you have so maybe that is the issue
I think we’ve just discovered the problem. I have Melodyne Editor and Cubase 13 LE. When I right click on the selected tracks, I don’t even see Extensions in the menu. (Is this an LE limitation?)
Well, darn! That’s a HUGE delta in bucks, beyond my current pocketbook. I guess I’ll have to soldier on with multiple windows, save up my simoleons. 
Thanks for the clarity y’all provided.
I just checked the Cubase 13 versions comparison chart, and ARA extensions are only available in Cubase Pro and Cubase Artist, so your using Cubase LE would explain the lack of this interface.
And, yeah, @glennloopez is correct about needing the high-end (Studio) version of Melodyne to get the multitrack functionality. I’d forgotten about that as I’ve had that version ever since the multitrack functionality became available.
