I'd like to know how I can see:
-chord/scale information from selected notes and selected regions.
AFAIK, there is not that feature (anymore) in Logic. If you hold down the chord notes on a keyboard, the LCD will display the held chord. The scale is something you set either in the (key) signature track, signature list or signature window
; or from within the LCD
which displays the currently active one. The control bar might need customization
to show that information.
Also, in the Piano Roll editor, you could select a specific scale from the local inspector and scale quantize notes
according to that selected scale.
-Also, on playback I don't see any chord or scale information.
As mentionned above, the played chord is realtime displayed in the LCD. Likely (?) you will have to fiddle in the Environment
to loop back the MIDI data stream back into the Sequencer Input object
in order to display the playback chords in the LCD, since the latter shows what is coming in Logic (from outside)... Not very convenient admittedly...
I would be really helpful for me.
What is the purpose of your request? What are you wishing to achieve exactly?
