program a marco. Alt 1 audio, alt 2 midi, alt 3 group etc. Currently alt and numbers above the keyboard are not assigned. Takes 1 minute. It’s in key commands under add track. You can also set it to bring up the general add track dialogue and decide on the type you want.
It should be part of the design. You should be able to do EVERYTHING within cubase with key commands. Mouse should be a optional thing to improve beginners usability.
