[LAU] Looking for MIDI Sequencer for Ubuntu 8.04.1 (ASUS Eee Version)

Hello -- this is my first post so I hope I am not starting out asking the wrong types of questions. I recently purchased a ASUS 900 with a 16 GB SSD. As many people do, I also installed the special Ubuntu Eee netbook version. Does a simple multitrack MIDI sequencer exist in binary form that will install easily using the ASUS series Net Books? Piano roll editing is sufficient. I need about 480 ppq. I am trying to reduce my dependence on Windows and except for the audio software I am accomplishing this with this $299 US computer. I am an experienced user of music software and prefer recording my piano tracks in MIDI as although I am a fair player I am not perfect and software to go in a visually fix timing or note errors would be very helpful. I naturally am interested in other types of audio software and have been researching the variety that exists but for some reason a cheap and dirty MIDI sequencer does not jump out at me. Thanks for your help. Frank Graves Spring, TX
