The real time kernel in intrepid is not working properly. If you want real time processing for audio you should either get back to hardy or downgrade your kernel to hardy's version. Try this one: Low latency howto - AlsaProject

I have tried the -RT kernel, but it messes up my GPU drivers and makes my resolution really small.  I have found that putting it in JACK mode helps a lot.

It wasn't too bad in Hardy but it's awful in Intrepid (sometimes >100msec). I have a midrange laptop with motherboard audio that isn't ideal for DAWing in Linux or Windows (Vista surprised me by being better than XP for this).

I keep LMMS around because I want to help develop it when I'm far enough into university software eng to know how.  I use FL Studio and Ardour/JACK-Rack for most of my music.

ardour.

1)  Plug in the keyboard.
2)  Open the instrument-track editor subwindow.
3)  Select the MIDI tab.
4)  Enable "Enable MIDI input".
5)  Click the button with a keyboard on it and select your keyboard from
the list of possible inputs.


It lags like crazy though.
