How do you use a keyboard with Audacity?

Assuming you're talking about recording MIDI - Audacity has no MIDI support or features (apart from displaying a MIDI file).



You need to be looking at a more fully-featured program, maybe even a full DAW (digital audio workstation).



Take a look at Reaper, which is very reasonably priced and has plenty of features comparable to much more expensive DAWs...

If you find Reaper limiting and you can spend a bit more, there's plenty of choice!



Sonar

Cubase

Ableton

FL Studio

Pro Tools (eww)

It as of yet can not do anything except display a midi file.
