Hello, I'm trying to record a song in Cubase, but I have a problem.

The SONG is a Pattern Chain that I converted to song.

This are the steps that I follow:
1) I open Cubase and choose multitrack MODX recording.
2) I sync up the Modx and the MODX connect.
3) I drag the song from the MODX Connect import window to the Cubase.

At this point, it seems to work: all tracks are separated, and all tracks sound (through the Modx and I can record the sound, so it should be the same song and the same sounds).

The problem is that there are differences between the song in Cubase and the song in the keyboard:

1) When the song changes of scene, in the Cubase it doesn't make the change as it is in the original song. For example, I have a track that in the SCENE 2 it starts to sound later than in the original song.
2) The instruments don't sound as in the original song. There are the same instruments (they sound through the Modx) but seems to change something (for example, a bass lost the sound between notes).

Thanks in advance.
