Hello

Those are great tutorials. Although the activate shortcut button exists inside vi pro sequencer I can confirm it does not work with the current version Cubase 11. When activated, it does freeze Cubase’s shortcuts but then the sequencer will not perform its shortcut keys. Maybe works fine for other daws.

I'm using the full vienna instrument pro 2 and the shortcuts don't work in the sequence mode inside your DAW (Cubase). What DAW were you using?
