or virtual keyboard
(best).
Not sure how just a virtual keyboard will help you but VMPK seems to be the most commonly
recommended one.

PS I have been doing a lot of sound recording and
editing with Linux and
a M-Audio interface (usually) and a PreSonus AudioBox 1818VSL when I
have to mostly into audacity. When I am absolutely forced to (when
using > 2 tracks where Audacity cannot cope yet) I use audacious. I
find audacious endlessly irritating for the same problems I outline
above, so many options, so many knobs, where do I start? But audacity
pretty much just worked.
Audacious is purely a media player. A pretty simple one at that! How do you do any editing
in a media player???
