looking through these it seems you're getting progressively better each snippet you make.

if you wanna get better with melodies i would recommend learning a little bit of music theory, learn your scales and chords.

anyways, keep up the good work and keep producing.
If you can bounce or render individual midi tracks as an audio file you can probably assure that you won't hear the "thank you for trying this demo" sylenth1 message, as long as it's a short segment
oh yeah
