I'm a hobbyist musician; for quite a while, I used a program for Mac's called 'Logic Pro', apparently this is the industry standard application for music creation. (Indeed, at my College if you don't have it at home you can't do any music courses)
So, is there anything like it for Ubuntu?
Please please PLEASE don't say "Audacity"; Logic Pro does so much more then edit audio (for example, I can quite easily create entire songs, minus the lyrics, by selecting instruments and their notes.) and Audacity is...well...laughable in comparison.
