Logical Editor - Fades, Transpose

Can you set up a macro to transpose up or down by semitones or a preset with up or down octave to key commands using the LE?

Can you set up a macro for x ms fades top and tail on a region with the LE?

Have a look at the factory presets. Also there is a built in command for octave transpose, I think it defaults to shift-arrow up, shift-arrow down.

Logical Editor is for MIDI, not audio.
