After allot of watching the synthesia vid and the midi file, I started to notice there is a difference between them. The lowest notes in the piano roll picture I posted. The midi file does what the picture shows. The synthesia vid however uses much longer notes for that part. My version in lmms, now...

I could not resist on adding drums, and am for now happy with them. 123 123 123 :P
Are you on Linux, and have you installed wine ?
Interesting. I think this piece how ever is high mid low, for the arpeggio part over and over again. Were the lower two notes are closer together. What I have now: Its not entirely right yet from bar 4 and on, but this basically is the part repeated throughout the whole track, Its not right yet beca...

I thought I was hearing the arpeggio going up and down, but its not that simple. :) Found were the the 1 2 3 sound come from. I think we can call it the bassline. Most left track in the synthesia vid. In lmms piano roll way...
I think its good, but the trumpet sound is too overwhelming (too loud) I think.

You can try adding reverb as somebody on soundcloud suggested.

I like that suggestion.
I had another look at the midi file, and I think its right. (I am for now only after note spacing and staying on the grid) Some midi files you import work 100%, this one works for 95% Although it plays fine, LMMS stays at default 4/4 and 140 bpm, and this is not right.
