I like to create my own music under Ubuntu. But it'S very hard to do this. There are some nice programs like lmms and qtractor. But you need some time to get into this programs and understand how they work. I just used the musicmaker from Magix to mix some songs. This program is very easy to use. There is a soundpool where you find good loops, timeshifting works and you can put effects on your loops. It's very easy to handle. Also using vst instruments is very easy. Everyone who likes to do his own music, can do this without any knowlege. It's great and it's BIG fun. I would be very happy if there would be the possibility to have a "ubuntu-solution" under a free licence.
