there are a few choices ardour is pretty good with a qbase interface also gnusound is similar in functionality but they are both realy writen for gnome, jokosher is a good kde composer alowing you to both record and compose using samples the interface however is a little simpler and is more for the garage band enthusiast.

if not check out ubuntu studio instal it along side your kde and select it at login

I use FlexiMusic Composer. Been very pleased with it. It is a good software for beginners and professionals, you may try to it.

If you really wish to compose music and do it right you will need program called LOGIC. You won't regret it I betcha!

heres a few to look up: Rosegarden lets you fiddle with score so you might like this one. Then theres qtractor and muse. For audio try ardour, LMMS for a fruity loops vibe..hydrogen for drums

most of them use qt dunno about ardour and lmms.
