In the menu selections accessed by the MENU button in the top right hand area of the GUI, you will find an option to check for updates.  This is great for when you are making changes to your DAW computer and you forget to go and update some of your EZkeys libraries.  I just caught myself and I should know better.

I bought Mellotoon yesterday with a Time Space discount and just noticed the same thing. Two weeks ago I got all caught up but nowI see there are more updates available.

Thanks Mod Bod - will use your tip to check that out.
