Hey Randy, how's it going :)!
It's me again, requesting scale selection previous/next buttons again, after 3 years. First requested in 2018, time flies :D.
I gave it a pass in 2020 to return with the same request in 2021.
This feature is still needed as I'm still not using Virta as much because it's hard to pick a scale that fits the rest of the song. Creating new files and/or picking or generating them feels nerdy and ruins the flow.
Hope to see the update one day! If you need any help with C++, I'm willing to do that for free (I'm experienced with plugin development, including UI and stuff).
I have a list of UI features like this to add to the next major version. This is on there. Thanks for the reminder.
