You can create scenes, these are groups of repeating chains, based on the 16 patterns that you create for a particular Project. This means that you might have a 2 pattern chain as an intro (scene 1), a 4 pattern chain as the verse (scene 2), a 2 pattern chain from verse to chorus (scene 3), a 4 pattern chain as the chorus (scene 4), and a 4 pattern chain as a bridge (scene 5). This would build a traditional style song with repeated phrasing. This is how you could build a 5 minute song with only 16 patterns per project, you just have to use repeated phrasing.
Scene: 1 - 2 - 3 - 4 - 3 - 2 - 3 - 4 - 3 - 5 - 5 - 3 - 4 - 4
Currently there is no way to chain scenes, you manually have to switch between them. The user community is actively asking for a scene-chain feature in the next frimware upgrade.
You are not able to record pitch bend, mod-wheel, or aftertouch - should you return it? This item has limitation, you'll have to decide that.
