you can get a simple program, "midikeys" that turns your laptop keyboard into a midi keyboard, which can help. i know they have it for mac, not sure about pc, and its free. try googling it.
if not the matrix pattern seqeuncer simplifies things for bass lines, lead lines etc, but if you want jazz like piano melodies, a midi keyboard is the only way to go......
