That's pretty sure! Yeah very wierd !
If you like to make music, and if you have a motivation+inspiration, you can make great stuff!
Now back to the topic...
Arpeggiator could be very usefull, as mentioned b4.
As for the melody, I can't help much, but try to make melody this way.
Play the rythm and bassline in the background(set to repet) and
over that, try to play live with keyboard, and then record the part you like.
Try varios melodies, something might work fot you.
Peace
