First i'd like to note, don't take anything I say to harshly, its not meant to be taken harsh.
I gave both tracks a quick listen, I like the opening to the first midi, but it soon fell apart at about 17 seconds when the second piano track came into play. Timing errors up the ying yang
. Are you using a metronome? If not, you oughta. Whats the name and brand of the midi controller your using?
The second track suffered from the timing errors instantly.. I suppose your recording each octaves part seperatly then combining them via tracks in the progam? Or are you playing it all out at one time?
Its a good start, but you have a VERY long way to go.
Edit: Sorry if nothing makes anysense that i typed, i'm a bit sick today and my brain isn't working quite right.
Sigs blow.
