Hello, I'm using the una corda vst. And my problem is that my sound in Ableton doesn't sound like in this video. https://www.youtube.com/watch?v=qYAD-_opG5M 1:43 and this is my own https://soundcloud.com/user-985159669-352651154 . What is wrong with that? I'm doing the same as he. But the final result is different.

I'm not sure what you're comparing here -- the first two chords of that progression..? It sounds like he voices the chords a little differently (with lower notes), or maybe there's just more processing on the track..
