I have not updated to 7 yet, but I did download the app to have a look at the manual and to poke around.
I noticed a new folder of Logical Editor presets called Musical Context, including such functions as “Delete Notes that do not match the current scale”, “Extract Alto” and others.
There is no specific mention of additions to the Logical Editor in the marketing material.
It sounds promising from a composing viewpoint! Has anyone played around with this, and are you willing to share your observations?
