The vocal sounds compressed and thin this maybe due to your mic/interface/ or standard effects employed
I didn't mean it was a backing track just that the VST instruments you have used sound just that - like synthetic instruments.
I think your voice / this tune would have worked better with a more natural feel and authentic instruments.
Well, sure, that is true. If this were to be a serious recording, I'd add a couple of real violin tracks.
Thats the one thing about garage band. The digital format does not grab vocals very well. Maybe with a serious condenser mic, and a pre-amp but I just used a Shure 58, straight in.
